электрокатализ

The core-shell type catalysts were obtained by spontaneous surface substitution of electrodeposited Pb, Ni and Cu by platinum metals Pt-Ru. The surface layer of obtained catalysts was tested by EDAX; the amount of platinum was determined by ICP-AES. The catalytic activity of obtained catalysts was examined in methanol oxidation reaction. The stationary state currents were referred to EAS, determined from hydrogen adsorption. For all investigated systems the catalytic effect was registered thus confirming the activity of core–shell catalyst.

The electrocatalytic activity of electrode materials synthesized by anodic selective dissolution of Ag–Pd alloys based on silver (4 and 8 at. % Pd) was studied. The kinetic laws of the electrooxidation of formic acid on compact palladium and anodically modified Ag,Pd-alloys in an acidic sulphate solution have been established.
