AB  - In the present study, synthesized macroporous copolymer was used for the sorption of lindane
from an aqueous solution. This organochlorine pesticide is classified, according to US EPA, as
mutagenic and teratogenic. Residues of lindane can persist in the environment, migrate long
distances, and cause widespread contamination. In this way, lindane residues can reach the
human body through the food chain. The usage of this pesticide is banned in most countries.
However, lindane remains a serious toxicological problem at industrial sites where lindane was
used coupled with improper wastewater disposal and has led to serious contamination. In
addition, some countries still allow the production and use of lindane, and despite localized
restrictions, lindane contamination remains a global problem. Taking into account these
reasons, its removal from the environment is of a great significance. The obtained macroporous
copolymer was syntesized via suspension copolymerization and was characterized by Fourier
transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The
parameters which affect sorption efficiency of the lindane were: pH, sorption time (tsor), ion
strength (ion), rpm, and dose of sorbent. These variables were optimized by the experimental
design which include Plackett-Burman Design (PBD) and Central Composite Design (CCD).
After screening step by the PBD, the optimum conditions were obtained by the CCD where the
values were investigated in two levels. The design of experiment showed that the ion strength
and dose of sorbent were the most significant parameters, while the other variables do not have
such an effect on sorption efficiency. Accordingly, the optimum conditions to reach the maximum
recovery were: pH 8, 180 min sorption time, 300 rpm, 2 w/v % ion strength and 8 g/l dose of
sorbent. The results showed that the studied copolymer could be an efficient sorbent for trace
lindane in water with recoveries above 80 %.

AB  - A novel porous gold polymer composite was prepared by the functionalization of a glycidyl methacrylate-based copolymer (pGME) with ethylene diamine (pGME-en), and activation by gold (pGME-en/Au), in a simple batch adsorption procedure in an acid solution, at room temperature. Detailed characterization of the pGME-en before and after activation was performed. The main focuses of this research were the design of a method that can enable the recovery of gold and the reuse of this multipurpose sorbent as an antimicrobial agent. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis pointed out amine groups as the primary binding sites for Au activation, while hydroxyl groups also contributed to the chelation reaction. pGME-en exhibited fast gold adsorption with an adsorption half-time of 5 min and an equilibrium time of 30 min. The maximal adsorption capacity was about 187 mg/g. The analysis of sorption experimental data with a non-linear surface reaction and diffusion-based kinetic models revealed the pseudo-second-order and Avrami model as the best fit, with unambiguous control by liquid film and intra-particle diffusion. The biological activity studies against Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, and Candida albicans revealed moderate activity of pGME-en/Au against different bacterial and fungal species. pGME-en/Au was stable in a saline solution, with a release of approximately 2.3 mg/g after 24 h.

AB  - A new magnetic amino-functionalized polymeric sorbent based on glycidyl methacrylate was synthesized and used in the separation of chromium Cr(VI) oxyanions sorption from aqueous solutions in a static batch system. The kinetic and isothermal parameters of the sorption process were determined. The experimental data were best fitted by a pseudo-second-order model with R2 = 0.994 and χ2 = 0.004. The sorption process of Cr(VI) removal by amino-functionalized sorbent was controlled by both intraparticle diffusion and liquid film diffusion. The equilibrium results showed that the sorption process is best described by the Freundlich model, followed closely by the Sips isotherm model, with a maximum sorption capacity of 64 mg/g. Quantum chemical modeling revealed that the sorption sites on the sorbent surface are fragments with diethylenetriamine and aminopropyl silane groups that coated the magnetic nanoparticles. The calculations showed that Cr(VI) oxyanions (Cr2O72−, CrO42− and HCrO4−) bind to both sorption sites, with diethylenetriamine centers slightly favored. The X-ray photoelectron spectroscopy (XPS) spectra demonstrate that the chromium bound to the sorbent in the form of Cr(III), indicating that the Cr(VI) can be converted on the surface of the sorbent to a less harmful form Cr(III) due to the sorbent’s chemical composition.

AB  - The impact of the type and amounts of nanofiller on the features of the glycidyl methacrylate-co-ethylene glycol dimethacrylate (GMA-co-EGDMA)/organomodified montmorillonite (OMt) nanocomposites that were prepared by in situ radical suspension polymerization, was examined. Cloisite 30B and Cloisite 25A were used in this study as nanofillers, in amounts of 2 and 10 wt.%. The structure, morphology, thermal stability and porosity of the initial GMA-co-EGDMA copolymer and their nanocomposites were examined by ATR-FTIR analysis, wide angle X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), transmission electron microscopy (TEM), thermogravimetric analysis (TG) and mercury porosimetry. It has been established that both clay nanofillers were successfully incorporated into the structure of the initial copolymer, simultaneously on their surface and also on cross-sectional area. Prepared samples with 2 wt.% have predominantly exfoliated, while samples with 10 wt.% have some tactoids-aggregates structure of the OMt layers. Thermogravimetric analysis revealed that after ~ 30 % of degradation, all nanocomposites become more thermal stable than the initial copolymer. The obtained results indicate that porosity parameters can be easily modified with the addition of clay nanofillers and thus prepared nanocomposites adjusted to specific purposes.

Утврђено је да су оба нанопуниоца глине успешно уграђена у структуру полазног кополимера, истовремено на његовој површини као и на површини попречног пресека. Добијени узорци са 2 мас.% имају претежно ексфолирану структуру слојева глине, док узорци са 10 мас.% показују присуство тактоидних-агрегатих слојева глине. Термогравиметријска анализа је показала да након ~ 30% деградације, сви нанокомпозити постају термички стабилнији од полазног кополимера. Добијени резултати указују да се параметри порозности могу лако модификовати додавањем нанопуниоца глине и на тај начин добити нанокомпозити прилагођени специфичним наменама.

Добијени узорци са 2 мас.% имају претежно ексфолирану структуру слојева глине, док узорци са 10 мас.% показују присуство тактоидних-агрегатих слојева глине. Термогравиметријска анализа је показала да након ~ 30% деградације, сви нанокомпозити постају термички стабилнији од полазног кополимера. Добијени резултати указују да се параметри порозности могу лако модификовати додавањем нанопуниоца глине и на тај начин добити нанокомпозити прилагођени специфичним наменама.",

AB  - In this report, magnetic porous polymer functionalized with pentaethylenehexamine (mP-PEHA) was tested as CO2 sorbent. The sorbent mP-PEHA was characterized by Fourier transform infrared spectroscopy in ATR mode (FTIR-ATR), scanning electron microscopy (SEM) and mercury porosimetry. CO2 adsorption was determined using a pulse gas chromatographic method. At optimal adsorption conditions (20 °C), the CO2 sorption capacity reached 10.8 ml CO2/g (0.48 mmol CO2/g). Temperature-programmed desorption (TPD) experiments were conducted to calculate the activation energy of CO2 desorption. Low activation energy (18.34 kJ/mol) and high desorption rate, with a stable uptake in five adsorption/desorption cycles, suggest mP-PEHA as potentially excellent sorbent for CO2 absorption.

AB  - In this paper, the influence of cobalt loading in pillared clay-supported cobalt materials on their electrocatalytic performance toward glucose oxidation was investigated. A series of aluminum-pillared montmorillonite clay (AP) materials with different cobalt loadings (x%CoAP, x = 1, 3, 5, and 10 wt%) was synthesized using the incipient wetness impregnation method. The X-ray powder diffraction (XRPD), inductively coupled plasma optical emission spectroscopy (ICP-OES), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy coupled with energy dispersive X-ray spectrometry (FE-SEM/EDX), high resolution transmission electron microscopy (HR-TEM) coupled with EDX, X-ray photoelectron spectroscopy (XPS), and low temperature N2 physisorption, were employed for characterization of the materials. The incorporation of cobalt in porous structure of pillared montmorillonite was confirmed. The synthesized materials (x%CoAP) were used for modification of carbon paste (CP) electrode and tested in reaction of glucose electrooxidation. The electrochemical measurements were conducted using cyclic voltammetry and chronoamperometry in a 1 M NaOH solution, with or without glucose. The results showed that the increase of cobalt loading improved the electrode performance toward glucose. The highest current response and sensitivity were obtained for the CP-5%CoAP electrode. A lower electrode performance of CP-10%CoAP was correlated with the presence of higher quantities of Co3O4 (confirmed by XRPD and XPS) in the electrode material. The mechanism and kinetics of glucose electrooxidation was studied in more details for the best performing electrode (CP-5%CoAP). It was found that the process was diffusion-controlled and the diffusion coefficient was determined. The charge transfer coefficient and catalytic rate constant were calculated. The electrode exhibited satisfactory repeatability, reproducibility, stability, and selectivity. The obtained results showed that appropriate amount of cobalt loading in pillared clay led to the obtainment of non-enzymatic electrode materials suitable for sustainable and green glucose sensors.

AB  - A novel magnetic polymer/bentonite composite was prepared by suspension copolymerization of glycidyl methacrylate and ethylene glycol dimethacrylate in the presence of magnetic bentonite (MB-PGME) and functionalized with ethylene diamine and hexamethylene diamine (MB-PGME-ED and MB-PGME-HD). The obtained samples were characterized in terms of structure as well as thermal, magnetic and morphological properties. The sorption of rhenium (Re) and tungsten (W) from aqueous solution onto MB-PGME-ED and MB-PGME-HD was investigated considering their contact time and different initial ion concentration, giving possibility for usage of these composites as commercial sorbents. The sorption system follows the pseudo-second order and intraparticle diffusion kinetic models. The results indicated a better fit with the Freundlich isotherm model.

AB  - The aluminum pillared clay (AP) was synthesized and impregnated with various cobalt loadings (x%CoAP, x=1, 3, 5, and 10 wt.%) by incipient wetness impregnation method. All samples were characterized by using X-ray powder diffraction (XRPD), inductively coupled plasma optical emission spectroscopy (ICP-OES) and low temperature N2 physisorption techniques. The chemical analysis confirmed the successful incorporation of cobalt in all impregnated samples. Nevertheless, only cobalt oxide (Co3O4) was identified for samples having higher cobalt contents. Furthermore, different cobalt loading was mainly affected the microporous region in such way that micropore surface area decreased with the increase of cobalt.

AB  - The goal of this work was the synthesis of a montmorillonite based catalyst for advanced oxidative degradation of organic water pollutants. Montmorillonite (Mt) –rich bentonite was acid-activated (MtA), and impregnated with cobalt (II) solution using the incipient wetness impregnation method. The impregnation was followed by heat treatment. Cobalt(II) ions were added in the quantities corresponding to 0.5 and 1.0 of the cation exchange capacity value. All samples were characterized by using chemical analysis, X-ray powder diffraction (XRPD), Electron paramagnetic resonance (EPR), X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM) coupled with Energy-dispersive X-ray spectroscopy (EDS), Transmission electron microscopy (TEM) and
low temperature N2 physisorption. The incorporation of the cobalt in the impregnated samples and the development of porous structure in the acid-activated ones were confirmed. The montmorillonite (Mt) was used as a catalyst support, while the cobalt in its oxide form was responsible for the generation of sulfo-radicals from Oxone®. Two aromatic N-compounds were tested as model pollutants: diazo dye - Acid Orange 10 (AO10) and nicotine. It was found that the synthesized catalysts could be used for the degradation of both pollutants, although more efficiently in AO10 degradation. The acid activation, higher cobalt loading, and temperature were found to be beneficial for the degradation of AO10.

AB  - Magnetic and non-magnetic macroporous crosslinked copolymers of glycidyl methacrylate and trimethylolpropane trimethacrylate were prepared by suspension copolymerization and functionalized with diethylenetriamine. The samples were characterized by mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy analysis (FTIR-ATR), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), atomic force microscopy (AFM), transmission electron microscopy (TEM) and SQUID magnetometry. The FTIR-ATR analysis of synthesized magnetic nanocomposites confirmed the presence of magnetite and successful amino-functionalization. Non-functionalized and amino-functionalized nanocomposites exhibited superparamagnetic behavior at 300 K, with a saturation magnetization of 5.0 emu/g and 2.9 emu/g, respectively. TEM analysis of the magnetic nanocomposite has shown that magnetic nanoparticles were homogeneously dispersed in the polymer matrix. It was demonstrated that incorporation of magnetic nanoparticles enhanced the thermal stability of the magnetic nanocomposite in comparison to the initial non-magnetic macroporous copolymer.

AB  - The presented study describes macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [PGME] functionalized with diethylenetriamine [PGME-deta] as a potential recovery agent for Mo(VI) oxyanions from aqueous solutions. Sorption studies were carried out by varying experimental conditions (pH, time, concentration, temperature). Kinetics of Mo(VI) sorption was investigated in batch (static) experiments, in the temperature range 298-343K. Sorption dynamics data were fitted to seven chemical-reaction and particle-diffusion models. The kinetics studies showed that Mo(VI) sorption adhered to the pseudo-second-order model under all investigated operating conditions. The sorption kinetics was determined to be governed by both the intraparticle diffusion and the external film diffusion to a lesser extent. The temperature rise promotes the molybdate species removal, with the maximum experimental uptake capacity of 4.02mmolg- 1 at 298K, at the selected pH which is consistent with the predominance range of hydrolized polynuclear Mo(VI) forms and optimum electrostatic attraction.

AB  - In this study, WO3 doped TiO2 powders were synthesized via sol-gel method combined with a hydrothermal process. The effect of sintering temperature on mesoporous structure and catalytic activities of these powders were investigated. The physical analysis via X-ray diffraction indicates that prepared samples are a mixture of anatase and rutile TiO2 phases. X-ray peak analysis is used to evaluate the crystallite size and lattice strain by the Williamson-Hall analysis. Considering all the reflections of the anatase phase the lattice strain ranging from c = 9.505 to c = 9.548 is calculated, suggesting that microstrain decreases when calcination temperature increases. N-2 adsorption-desorption analysis shows that the surface area and pore volume decrease with increasing temperature and that WOx-TiO2 powders primarily consist of mesopores. Sintering temperature induced a change in textural properties causing a systematic shift towards larger mesopores. Simultaneously, photoactivity in decolorization of methyl orange increases with increasing calcination temperature up to 700 degrees C, followed by significant decrease with its further increase.

AB  - Introduction: The outcome of periapical surgery has been directly improved with the introduction of novel material formulations. The aim of the study was to compare the retrograde obturation quality of the following materials: calcium silicate (Biodentine; Septodont, Saint-Maur-des-Fosses, France), mineral trioxide aggregate (MTA+; Cerkamed Company, Stalowa Wola, Poland), and glass ionomer cement (Fuji IX; GC Corporation, Tokyo, Japan). Methods: Materials' wettability was calculated concerning the contact angles of the cements measured using a glycerol drop. Cements' porosity was determined using mercury intrusion porosimetry and micro computed tomographic (mu CT) imaging. Extracted upper human incisors were retrofilled, and mu CT analysis was applied to calculate the volume of the gap between the retrograde filling material and root canal dentin. Experiments were performed before and after soaking the materials in simulated body fluid (SBF). Results: No statistically significant differences were found among the contact angles of the studied materials after being soaked in SBF. The material with the lowest nanoporosity (Fuji IX: 2.99% and 4.17% before and after SBF, respectively) showed the highest values of microporosity (4.2% and 3.1% before and after SBF, respectively). Biodentine had the lowest value of microporosity (1.2% and 0.8% before and after SBF, respectively) and the lowest value of microgap to the root canal wall ([10 +/- 30] x 10(-3) mm(3)). Conclusions: Biodentine and MTA possess certain advantages over Fuji IX for hermetic obturation of retrograde root canals. Biodentine shows a tendency toward the lowest marginal gap at the cement-to-dentin interface.

AB  - Magnetic macroporous crosslinked copolymer glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) samples with different magnetite content were prepared by suspension copolymerization and functionalized with diethylene triamine. Samples were characterized by elemental analysis, mercury porosimetry, Fourier transform infrared spectroscopy (FTIR) analysis, scanning electron microscopy with energy-dispersive X-ray spectroscopy, transmission electron microscopy, SQUID magnetometry and X-ray photoelectron spectroscopy (XPS). The selected amino-functionalized sample was tested as a potential sorbent for the Mo(VI) and Re(VII) oxyanions from aqueous solutions. The influence of pH, ionic strength and possible interfering of cations and anions was investigated. Equilibrium data were analyzed with Langmuir, Freundlich and Tempkin adsorption isotherm models. Sorption studies were carried out in a batch competitive experiments, in the pH range 1-8, at 298 K. Obtained results indicate that 92% of Re(VII) and 98% of Mo(VI) were sorbed at pH 2.

AB  - Hybrid polymer/nanocomposites are a new class of materials that consist of polymer
matrix and clay nanoparticles as the dispersed phase. The aim of this work was to obtain
macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)/clay
nanocomposites p(GEM-NC) with different porosity and morphology.
Macroporous p(GEM) copolymer and two nanocomposite p(GEM-NC) samples with
different clay content (2 and 5 wt.%) were synthesized by in situ suspension
copolymerization. Nanocomposite samples were reinforced with organomodified
montmorillonite clay Cloisite 30B (C30B). Structure, porosity and surface chemistry of the
p(GEM) and p(GEM-NC) samples were evaluated by Fourier transform infrared spectroscopy
(FTIR), scanning electron microscopy with energy dispersive x-ray spectroscopy (SEM/EDS)
and mercury porosity.
The results show the synthesized p(GEM-NC) have improved textural, structural and
morphological properties in comparison with pure macroporous p(GEM) copolymer. The
incorporation of C30B in p(GEM) was confirmed by FTIR and SEM/EDS analysis. Also, it
was shown that the higher clay content significantly influences the p(GEM-NC) porosity
parameters (i.e. specific surface area, specific volume and pore diameter).

AB  - In this study, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) was synthesized by suspension copolymerization, functionalized by ring-opening reaction of the pendant epoxy groups with diethylene triamine and used for immobilization of Pd(II) ions from chloride and nitrate solutions under batch experimental condition. The amino-functionalized sample and samples with immobilized Pd(II) ions were characterized by Fourier transform infrared spectroscopy (FTIR) analysis and scanning energy-dispersive X-ray spectroscopy (SEM-EDX). The electrochemical behavior of electrodes composed of synthesized samples was tested in 0.1 M H2SO4 by means of cyclic voltammetry (CV). The shape of recorded CV showed dependence on the type of Pd-salt used for Pd immobilization. The reaction of oxidation of 4-chlorophenol (4-CP) from 0.1 M H2SO4 at investigated samples was also studied. Electrooxidation of 4-CP resulted in passivation and formation of reversible hydroquinone/benzoquinone on both investigated electrodes, although hydroquinone/benzoquinone formation was more pronounced on Pd immobilized from nitrite solution.

AB  - This article presents the comparison of structural and fractal properties of nanocrystalline titanium dioxide (TiO2) and TiO2 modified with tungstophosphoric acid (TiO2/HPW) and their impact on the photocatalytic degradation of hazardous water pollutants. TiO2 and TiO2/HPW samples were synthesized by a combined solgel and hydrothermal processing. The XRD analysis of pure TiO2 samples revealed that phase composition was mainly dependent on the calcination temperature, changing from amorphous TiO2 to crystalline anatase and rutile by increasing the temperature. On the other hand, the XRD of TiO2/HPW samples calcined at temperatures above 600 degrees C showed crystalline peaks associated to formation of WO3 and WO2.92 crystalline domains. The N-2 adsorption-desorption isotherm and pore size distribution of TiO2/HPW samples detected the existence of mesoporous characteristic with very narrow bimodal pores in the mesoporous region. The structural heterogeneity of samples was analyzed by means of pore size distribution functions, while the variation in fractal dimension were determined from the nitrogen adsorption isotherms, using the modified Frenkel-Halsey-Hill method. The results demonstrate that the approach is capable of characterizing complex textures such as those present in the TiO2 and TiO2/HPW photocatalysts. Besides, the effect of calcinations condition on photocatalytic properties of the samples was also investigated. The highest efficiency with respect to methyl orange photodecomposition was observed for TiO2/HPW photocatalysts calcined at 700 degrees C.

AB  - Bone is a remarkable biological nanocomposite material showing peculiar hierarchical organization from smaller (nano, micro) to larger (macro) length scales. Increased material porosity is considered as the main feature of fragile bone at larger length-scales. However, there is a shortage of quantitative information on bone porosity at smaller length-scales, as well as on the distribution of pore sizes in healthy vs. fragile bone. Therefore, here we investigated how healthy and fragile bones differ in pore volume and pore size distribution patterns, considering a wide range of mostly neglected pore sizes from nano to micron-length scales (7.5 to 15000 nm). Cortical bone specimens from four young healthy women (age: 35 +/- 6 years) and five women with bone fracture (age: 82 +/- 5 years) were analyzed by mercury porosimetry. Our findings showed that, surprisingly, fragile bone demonstrated lower pore volume at the measured scales. Furtnermore, pore size distribution showed differential patterns between healthy and fragile bones, where healthy bone showed especially high proportion of pores between 200 and 15000 nm. Therefore, although fragile bones are known for increased porosity at macroscopic level and level of tens or hundreds of microns as firmly established in the literature, our study with a unique assessment range of nano-to micron-sized pores reveal that osteoporosis does not imply increased porosity at all length scales. Our thorough assessment of bone porosity reveals a specific distribution of porosities at smaller length-scales and contributes to proper understanding of bone structure which is important for designing new biomimetic bone substitute materials.

Furtnermore, pore size distribution showed differential patterns between healthy and fragile bones, where healthy bone showed especially high proportion of pores between 200 and 15000 nm. Therefore, although fragile bones are known for increased porosity at macroscopic level and level of tens or hundreds of microns as firmly established in the literature, our study with a unique assessment range of nano-to micron-sized pores reveal that osteoporosis does not imply increased porosity at all length scales. Our thorough assessment of bone porosity reveals a specific distribution of porosities at smaller length-scales and contributes to proper understanding of bone structure which is important for designing new biomimetic bone substitute materials.

AB  - Porous monolithic glycidyl methacrylate (GMA) and ethylene glycol
dimethacrylate (EGDMA) copolymer [PGME] and three composite samples with
alumina (PGME/alumina) were synthesized by radical copolymerization in a cast
and functionalized by reaction of diethylene triamine (deta) with epoxy groups in
GMA. All the samples were characterized using FTIR-ATR spectroscopy, SEM,
AFM, solid state NMR, thermogravimetry and mercury porosimetry. Additionally,
amino functionalized PGME/alumina with the highest alumina content
(PGME/alumina50-deta) was loaded with chromium [Cr(VI)] ions. Kinetics of Cr
(VI) sorption was investigated in batch static experiments, at 298 K and pH = 2, for
various initial concentrations (Ci = 0.5, 1.5 and 2.5 mM) and analyzed using three
kinetic models. Cr(VI) sorption by PGME/alumina50-deta obeys the PSO kinetic
model, while IPD model suggests some degree of intraparticle pore diffusion control.

AB  - Novel macroporous functionalized copolymers with different cross-linker concentrations and porosity parameters were synthesized by reaction of the pendant epoxy groups of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (poly(GMA-co-EGDMA)) with hexamethylene diamine 1,3-bis(3-aminopropyl)tetramethyldisiloxane, and alpha,omega-diaminopropyl poly(dimethylsiloxane). The copolymers were prepared in forms, of spherical beads and characterized by Fourier transform infrared (FTIR); C-13 and Si-29 solid-state NMR, mercury porosimetry, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Copolymers prepared with the higher cross-linker concentrations have better thermal stability, higher glass transition temperatures; higher specific surface areas, and smaller pore diameters that correspond to half Of the pore volumes. Out results show that functionalization significantly changed porosity parameters, mechanism of thermal degradation; and increased thermal, stability in comparison with the initial copolymers. These macroporous copolymers could potentially have many applications, i.e. for sorption of heavy and precious metals or as Material for gas chromatography columns.

AB  - This paper provides the correlation between the catalytic activity and selectivity of catalysts with various loadings of heteropolyacids over bentonite in the vapour phase 2-propanol oxidation. The catalysts are characterised by energy dispersive spectroscopy, differential scanning calorimeter, ammonia temperature programmed desorption, infrared spectroscopy and a nitrogen adsorption/desorption method. Energy dispersive spectroscopy results have shown satisfactory agreement regarding chemical composition that corresponds to the desired content of heteropolyacids on bentonite. Thermal analysis confirmed the thermal stability of catalysts under the investigated region of oxidation reaction. NH3-TPD spectra demonstrated that all catalysts include two types of acidic sites: weak adsorption centres up to 390 K and a broad distribution of stronger acidic sites at higher temperatures. The catalysts were active in the vapour-phase conversion of 2-propanol to acetone in the temperature region of 343-553 K. An increase of HPW loading improves selectivity towards acetone formation.
