Abstract

Baked carbon containing impregnated vanadium may be electrochemically oxidized to CO2 in 1 M H2SO4 at 80–90% current efficiency during prolonged electrolysis (>20 h) at 70°C under an applied potential of 1.0 V versus saturated calomel electrode (SCE). The vanadium is electrocatalytically maintained in the highest oxidation state with an activation energy of 44–80 kJ mol−1 at temperatures up to 80°C.
