摘要：

The present study reports cyclic voltammetric and a.c. impedance spectroscopy investigations of electrooxidation process of ethanol on Pt catalytic surfaces, carried-out in 0.5 M H2SO4 solution. The kinetics of ethanol electrooxidation were examined on polycrystalline Pt, Pt(111) and (100) single-crystal surfaces, also in relation to those of the process of underpotential deposition (UPD) of H at Pt. In reference to the temperature dependence, electrochemical examinations were performed for variable temperature range, from 23 through 60 degrees C.
