Cyclic voltammetry as a tool for model testing of catalytic Pt- and Ag-doped carbon microspheres

Popis výsledku v původním jazyce

This paper deals with comparison of modified carbon electrodes prepared from Pt- and Ag-doped carbon microspheres using cyclic voltammetry of [Fe(CN)(6)](3-)/[Fe(CN)(6)](4-) redox pair as a probe under various experimental conditions. Spherical particlesranging from 0.5 to 8 mu m in average as evidenced by SEM showed slight influence of dopant nature onto their microstructure. FTIR analysis revealed that the involvement of metal species in the carbon structure was followed by their subsequent reductionand rising of oxidized carbon functionalities in the spectra. Electrochemical study showed that all the examined electrodes performed reversible processes with chemically stable generated products and no side chemical reactions. Among them, Pt-doped electrode showed superior electrocatalytic behavior in terms of heterogeneous transfer rate constant and other kinetic parameters. Since minimal addition of Pt in the hydrothermal synthesis resulted in powerful electrocatalytic effect as pre
