Abstract

Pd(WC1–x)/C-electrodes were obtained by redox reaction between Pd2+ ions and tungsten carbide WC1–x. The palladium mass released in 2 h from of 0.1 M PdCl2 + 0.5 M H2SO4 solution is 0.60 ± 0.03 mg/cm2 (the electrode geometric surface); the specific surface area is 8.5 m2/g. The palladium is found to be reduced to a zero oxidation degree during currentless deposition; the basic products of WC1–x oxidation are tungsten oxides. The catalytic effect of the Pd(WC1–x)/C-electrodes in the hydrogen evolution reaction and oxidation of formic acid reaction has been discovered.
