AB  - Cobalt molybdate is of importantce for the development of mobile telecommunication systems, such as mobile phones and high-quality microwave dielectric ceramics for high resonant frequency selectivity in microwave devices. Due to their special catalytic properties, cobalt molybdates have been used as catalysts in many chemical and petrochemical processes. The CoMoO4 nanoparticles ware synthetized in a simple, quick, and inexpensive way, by using a glycine nitrate procedure (GNP), with and without calcination at 450 °C [1], and investigated by applying the Briggs-Rauscher oscillatory reaction method [2]. The complex oscillatory BR reaction is sensitive to different insoluble analyte addition [3]. This feature of BR oscillatory reaction is used to investigate effect of different masses of GNP synthetized (with and without calcination at 450 °C) CoMoO4 samples on oscillatory dynamics. These two samples give the complete different effects in BR reaction. Obtained results strongly suggest that BR oscillatory reaction could be used for distinguishing these two samples, opening new direction in the investigation of ceramics materials.

AB  - The main aim of this research is to show influence of different hydroxides, applied in carbon materials activation process on the electrochemical properties of activated carbon samples. The carbon material samples were prepared by hydrothermal treatment of sucrose and thermally activated using KOH, NaOH and LiOH by chemical activation method. The electrochemical properties of the obtained carbon material samples were examined by cyclic voltammetry and electrochemical impedance spectroscopy and correlated to their physicochemical properties. Investigated samples showed characteristic capacitor-like behavior. The best result of specific capacitance was obtained for the sample synthesized treated by KOH, while the increase in capacitance follows the arrangement of the growth of ionic radius of a metal from an alkali which is used for activation. Dependence on the type of hydroxide is due to differences in the radii of a metal. The alkalis with larger radii of metal produce wider pores and consequently the structure of a porous layer become more accessible and available to the charge transfer of capacitive response.

AB  - Thermo-chemical conversion via the pyrolysis of cigarette butt (CB) filters was successfully valorized and upcycled in the pre-carbonization and carbonization stages. The pre-carbonization stage (devolatilization) of the precursor material (cellulose acetate filter, r-CAcF) was analyzed by micro-scale experiments under non-isothermal conditions using TG-DTG-DTA and DSC techniques. The results of a detailed kinetic study showed that the decomposition of r-CAcF takes place via complex mechanisms, including consecutive reaction steps and two single-step reactions. Consecutive stages include the α-transition referred to as a cellulose polymorphic transformation (cellulose I → II) through crystallization mechanism changes, where a more thermodynamically ordered system was obtained. It was found that the transformation rate of cellulose I → II (‘cellulose regeneration’) is strongly affected by the presence of alkali metals and the deacetylation process. Two single-step reactions showed significant overlapping behavior, which involves a nucleation-controlled scission mechanism (producing levoglucosan, gaseous products, and abundant radicals) and hydrolytic decomposition of cellulose by catalytic cleavage of glycosidic bonds with the presence of an acidic catalyst. A macro-scale experiment showed that the operating temperature and heating rate had the most notable effects on the total surface area of the manufactured carbon. A substantial degree of mesoporosity with a median pore radius of 3.1695 nm was identified. The presence of macroporosity on the carbon surface and acidic surface functional groups was observed.

AB  - Carbon materials with developed porosity are usually used as supports for platinum catalysts. Physico-chemical characteristics of the support influence the properties of platinum deposited and its catalytic activity. In our studies, we deposited platinum on carbon fibrous like materials obtained from platanus seeds-achenes. The precursor was chemically activated with different reagents: NaOH, pyrogallol, and H2O2, before the carbonization process. Platinum was deposited on all substrates to study the influence of the substrate properties on the activity of the catalyst. Carbon materials were characterized by nitrogen adsorption/desorption isotherms measurements, X-ray diffraction, and scanning electron microscopy. It was noticed that the adsorption characteristics of carbon support affected the structure of platinum deposits and thus their activity.

AB  - In this work, plane tree seed-based activated carbons were characterized in detail for a variety of applications. The particularly important area of application would be in the artificial photosynthesis. After carbonization process of biomass precursor at 650°C, the resulting preliminary activated carbons were activated at various temperatures. The activated carbons were characterized by oxygen functionalities (a particularly important role has ester oxygen groups) which provide a unique microstructure. The chemical compositions of as-prepared activated carbons were analyzed through Fourier transform infrared and Raman spectra as well as gas chromatography–mass spectroscopy analysis, while morphology was observed by scanning electron microscopy analysis. Applied analysis showed that detected graphite mainly becomes uniformly nanocrystalline system. The current study also explored the applicability of carbon material obtained from plane tree seed as a potential gaseous adsorbent. The characterization showed that the tested material contains both mesopores and micropores, and this should be advantageous for the gas sorption process, since mesopores may provide low-resistant pathways for the diffusion of CO2 molecules, while the micropores are the most suitable for trapping of CO2. The sorption process analysis (including adsorption/desorption isotherms behavior) shows indication that the rate-limiting step of CO2 adsorption onto activated carbon is probably governed by diffusion-controlled process, especially at temperatures below 850°C.

AB  - The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) would allow creation of highly porous and spatially distinct ordered bio-SiC ceramics. The results of carbonization experiments at several operating temperatures and activation of carbons with multiple-cycle treatments TEOS clearly showed the possibility of obtaining SiC nano-structures, after performing the carbothermal reduction at 1400 °C. The increase in the activation temperature and the duration time starts the development of the SiC particles inside the porous structure. The XRPD analysis showed that the major SiC polytype has cubic SiC (β-SiC) structure and remainder is hexagonal SiC polytypic (α-SiC) structure. It was established that the carbons obtained from carbonization of the Platanus orientalis L. plane tree fruit (PTF) precursor and activated at 850 °C with longer holding times (1 and 2 h) exhibit β-SiC (cubic) nano-wires. A possible nano-wires increment mechanism was suggested. The obtained results represent significant contribution in understanding the process as well as the main characteristics of SiC nano-materials and their possible applications.

AB  - Activated carbon was prepared using plane tree seed as a cheap and renewable raw material. The samples were prepared by carbonization under N-2 atmosphere up to 850 degrees C, and activation in CO2 atmosphere at different both temperatures (750 and 850 degrees C) and times of activation (0.3,1 and 2 h). The influence of activation parameters on physicochemical properties was studied by XRPD, Raman spectroscopy, FTIR, N-2 physisorption, SEM and electrochemical methods. The pore structure was correlated to the specific capacitance and the amount of hydrogen stored, in alkaline, neutral and acidic electrolyte solution. The relationship of asymmetrical shape of CV curves with the porosity of samples has served to better understand some unclear issues related to the complex mechanism of charge storage. The sample activated at 850 degrees C for 2 h displayed the best behavior. At a high scan rate of 300 mV s(-1), its capacitance, amounted to similar to 26.8 mu F cm(-2) 19.69 mu F cm(-2) and 25.8 mu Fcm(-2) in KOH, Na2SO4, and H2SO4 solutions, respectively.

AB  - Microporous zeolite templated carbon (ZTC) was synthesized by impregnation method using zeolite Y (Na-form) as a template, and furfuryl alcohol as a carbon precursor. The characterization was carried out by X-ray diffractometry, Raman spectroscopy, scanning electron microscopy, nitrogen physisorption, elemental analysis and electrochemical methods. Physisorption measurements evidenced high micro pore volume of obtained material (similar to 0.43 cm(3) g(-1)). The charge storage ability in aqueous KOH, H2SO4 and Na2SO4 solutions was systematically studied by cyclic voltammetry, galvanostatic charging/discharging and complex impedance measurements. Specific coulombic capacitance, the hydrogen storage, H-ZTC bonding and relaxation time of adsorption were found to be dependent on the type of electrolyte. Neutral Na2SO4 aqueous solution was found to be the best for supercapacitor application, thanks to: i) the highest available voltage window ii) lowest corrosion and iii) highest capacitance amounting to 123 F g(-1) at 1 A g(-1)

AB  - Nanostructures of noble metals (Pt and Ag) on carbon support were prepared from fructose and solution of the Nobel metal salts (H2PtCl6 x 6H2O or AgNO3) under hydrothermal conditions. Commercial fructose (C6H12O6) acts as the carbon source and reducing agent and noble metal salts is a source of the metal to be incorporated in the new formed carbon material structure. The crystalline structure was examined by X-ray diffraction (XRD) and morphology investigated by scanning electron microscopy (SEM). The crystallite size of the deposited particles could be estimated by evaluating the line width of the Bragg peak applying the Scherrer method. All the XRD patterns clearly show the five main characteristic peaks of the face-centered cubic (fcc) crystalline for both Pt and Ag crystallite. The obtained Pt crystallite sizes were below 5.5 nm, while the Ag crystallite sizes were about 32 or 34nm.

Komercijalna fruktoza (C6H12O6) deluje kao izvor ugljenika i redukujući agens, a soli plemenitih metala, kao izvor metala, koji treba da se inkorporira u novonastalu strukturu ugljeničnog materijala. Kristalita struktura je ispitivana pomoću difrakcije X-zraka (XRD) a morfologija je ispitivana pomoću skanirajuće elektronske mikroskopije (SEM).
