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  - In this work, surface characteristics of different carbon materials were investigated. The materials under consideration were: activated carbon, carbon monolith, carbon felt and glassy carbon (powder, plate and broken plate). The surface functional groups of the studied carbon materials were determined by Boehms method and point of zero charge by mass titration. The specific surface area was studied by BET method with N-2 adsorption. As a specific test for surface activity, cementation of silver from aqueous solution of silver salts was used. The rate of silver deposition on the carbon materials was studied as a function of immersion time (AgNO3 concentration 75 mg/dm(3)), as well as a function of concentration of AgNO3 solution (25, 50, 75, 100, 125 mg/dm(3)) by atomic absorption spectrometry (AAS) to determine the concentration of Ag in the solution. The morphology of silver coatings was characterized by scanning electron microscopy (SEM) and structural characteristics by X-ray diffraction. The results obtained show that metallic silver deposits were formed at the surface of all examined samples. Oxygen complexes at the surface of glassy carbon samples were analysed by temperature programmed desorption (TPD) before and after silver deposition in order to establish the mechanism of silver deposition.
