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  - An ultrasonic irradiation was applied for the impregnation by chemical agents in the chemical activation process of new type of active carbon precursor. Plane tree seed, due to the unique fibrous structure and low cost is a promising eco-friendly raw material for the preparation of activated carbon materials. Ultrasonic irradiation was used for the impregnation step allowing the chemical activation by different agents: potassium or sodium hydroxide, hydrogen peroxide and pyrogallol. The porous structures were examined by nitrogen adsorption/desorption isotherms at 77 K and electrochemically by cyclic voltammetry. The textures of these materials were observed by scanning electron microscopy. The application of ultrasonic irradiation in the impregnation step increased surface area of the final material more than two times in comparison to the material which impregnation in the activation process was by conventional stirring. Ultrasonic irradiation enhances the chemical activation process and the activated carbon fibrous materials with nanoporous structure were obtained by impregnation of seeds with alkaline hydroxides. Total surface areas of these samples were 976 m(2) g(-1), and 1130 m(2) g(-1). These fibers have total specific capacitance as high as 125 F g(-1) and 53 F g(-1) which major fraction in both cases originate from internal micropores structure.

AB  - Active carbon hollow fibers were prepared from regenerated polysulfone hollow fibers by chemical activation using: disodium hydrogen phosphate 2-hydrate, disodium tetraborate 10-hydrate, hydrogen peroxide, and diammonium hydrogen phosphate. After chemical activation fibers were carbonized in an inert atmosphere. The specific surface area and porosity of obtained carbons were studied by nitrogen adsorption-desorption isotherms at 77 K, while the structures were examined with scanning electron microscopy and X-ray diffraction. The activation process increases these adsorption properties of fibers being more pronounced for active carbon fibers obtained with disodium tetraborate 10-hydrate and hydrogen peroxide as activator. The obtained active hollow carbons are microporous with different pore size distribution. Chemical activation with phosphates produces active carbon material with small surface area but with both mesopores and micropores. X-ray diffraction shows that besides turbostratic structure typical for carbon materials, there are some peaks which indicate some intermediate reaction products when sodium salts were used as activating agent. Based on data from the electrochemical measurements the activity and porosity of the active fibers depend strongly on the oxidizing agent applied.
AB  - Aktivna ugljenična šuplja vlakna su dobijena hemijskom aktivacijom polisulfonskih šupljih vlakana pomoću rastvora dinatrijum-vodonik-fosfata-2-hidrata, dinatrijum-tetraborata 10-hidrata, vodonik-peroksida i diamonijum-vodonik-fosfata. Nakon hemijske aktivacije, vlakna su karbonizovana u inertnoj atmosferi. Specifična površina i poroznost dobijenih vlakana su ispitivana preko izotermi adsorpije-desorpcije azota na 77 K, dok je struktura ispitivana skenirajućom elektronskom mikroskopijom i rendgenskom difrakcijom. Proces aktivacije poboljšava adsorpciona svojstva vlakana, što je naročito izraženo kod aktivnih šupljih vlakana aktiviranih pomoću dinatrijum-tetraborata-10-hidrata i vodonik-peroksida. Aktivna ugljenična šuplja vlakna su mikroporozna sa različitom raspodelom veličine pora. Hemijskom aktivacijom fosfatima dobija se aktivan karbonski materijal male specifične površine, ali sa mezoporoznom i mikroporoznom strukturom. Rendgeno-strukturna analiza, pored turbostratične strukture, tipične za ugljenične materijale, ukazuje na prisustvo nekih intermedijarnih jedinjenja nastalih u toku procesa aktivacije solima natrijuma. Na osnovu elektrohemijskih merenja može se zaključiti da aktivnost i poroznost aktivnih vlakana strogo zavise od primenjenog aktivacionog agensa.

AB  - Nickel thin films were deposited on glass substrates at different N2 gas contents using a dc triode sputtering deposition system. Triode configuration was used to deposit nanostructured thin films with preferred orientation at lower gas pressure and at lower substrate temperature compared to the dc diode sputtering system. A gradual evolution in the composition of the films from Ni, Ni(N), to Ni3N was found by X-ray diffraction analysis. The preferred growth orientation of the nanostructured Ni films changed from (1 1 1) to (1 0 0) for 9% N2 at 100 °C. Ni3N films were formed at 23% N2 with a particle size of about 65 nm, while for 0% and 9% of nitrogen, the particles sizes were 60 nm, and 37 nm, respectively, as obtained by atomic force microscopy. Magnetic force microscopy imaging showed that the local magnetic structure changed from disordered stripe domains of about 200 nm for Ni and Ni(N) to a structure without a magnetic contrast, indicating the paramagnetic state of this material, which confirmed the structural transformation from Ni to Ni3N.

AB  - Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself as well as of a catalyst. In our studies we deposited platinum on hollow fibers with or without carbon cryogel. Carbon materials were characterized by nitrogen adsorption/desorption isotherms measurements, X-ray fluorescence spectrometry and scanning electron microscope. Deposition of platinum was performed chemically and electrochemically. The electrochemical deposition was performed on the grinded samples at the same conditions for all substrates with the aim to study the activity of the catalyst. It was noticed that the nature of carbon support affected structure of platinum deposits and thus their activity.

AB  - The influence of nitrogen ion bombardment during e-beam triode ion plating of nickel on the microstructure and film orientation has been investigated. The deposition variables explored were the ion current density and deposition rate while the substrate temperature (ambient), partial pressure of nitrogen (3 x 10(-4) Torr) and substrate bias potential (4.5kV) were constant. The orientation and growth morphology change for films about 1 mu m thick were determined by XRD, SEM and STM method. The preferred orientation changes from (111) to nearly complete (200) as a function of ion to atom arrival ratio (IAR), and was independent of the substrate type (amorphous or monocrystalline). The ion beam bombardment of films after deposition enables the in depth determination of the nickel texture change during growth. For the highest IAR value the complete (200) texture was achieved at the beginning of deposition. The surface morphology (STM) and preferred orientation changes were correlated with ion to atom flux ratio and discussed on the basis of lowering the overall energy of the film.
