AB  - We report a particular method of Pt/glassy carbon (GC) surface formation, based on a 15 key H(+/-) ion beam irradiation of thin H(2)PtCl(6)xnH(2)O layer placed over the GC surface. Hydrogen-ion beam irradiation provided an excellent adherence of Pt deposit, unlike to any other Pt-deposition method. Furthermore, the morphology and electrochemical activity of GC/Pt catalyst obtained at the fluence of 5 x 10(17) cm(-2) was found to be sensitive to the sign of charge of hydrogen ions. The electrochemical activity of such obtained Pt/GC surface toward oxygen reduction and ethanol oxidation was compared with the activity of the Pt deposits obtained by other more common reduction procedures.

AB  - The surface of carbon monolith (CM) was chemically treated in order to obtain antibacterial filters with silver deposit for water treatment. The chemical treatment involved submerging the as-received CM in HNO(3), KOH and H(2)O(2) solution. The specific surface area was examined by N(2) adsorption. Silver deposition at the surface of CM samples was performed using cheap and simple procedure of immersing CM samples in aqueous solution of AgNO(3). Temperature programmed desorption method has been used in order to investigate the nature and thermal stability of surface oxygen groups before and after silver deposition. The composition and crystalinity of silver deposits have been examined by X-ray diffraction. Chemical treatment does not cause any drastic changes of CM specific surface area, but increases a total amount of surface oxides. Amount of deposited silver is several times higher for all chemically treated samples. The results show that increasing the amount of CO yielding groups on CM surface leads to increased amount of Ag deposit and decreases its crystallite sizes

AB  - Carbon monolith was treated with HNO3, KOH and H2O2. Effects of these treatments on the surface functional groups and on the amount of silver deposited on the CM surface were studied by temperature programmed desorption (TPD) and atomic absorption spectrometry (AAS). As a result of chemical treatment there was an increase in the amount of surface oxygen complexes. The increase in the amount of silver deposit is proportional to the amount of surface groups that produce CO under decomposition. However, the high amount of CO groups, decomposing above 600°C, induces the smaller Ag crystallite size. Therefore, the high temperature CO evolving oxides are, most likely, the initial centers for Ag deposition.
AB  - Karbon monolit (KM) tretiran je rastvorima HNO3, KOH i H2O2. Uticaj tretmana na površinske funkcionalne grupe i na količinu izdvojenog srebra na površini KM-a ispitivan je temperaturski programiranom desorpcijom (TPD) i atomskom apsorpcionom spektrometrijom (AAS). Tretman svim navedenim rastvorima dovodi do povećanja količine površinskih kiseoničnih grupa, a količina izdvojenog srebra je proporcionalna količini grupa koje dekompozicijom daju CO. Visoko-temperaturske fenolne, karbonilne, etarske i hinonske grupe, koje dekompozicijom daju CO iznad 600°C, predstavljaju inicijalne centre za rast kristalita Ag, a veličina kristalita srebra je obrnuto proporcionalna koncentraciji ovih visoko-temperaturskih grupa na površini KM.
