Catalytic Effects of Chlorate Ions on the Electrode Reaction Processes of 12-Molybdophosphate and 12-Molybdosilicate

The third cathodic waves corresponding to the reduction processes from the four-electron to the six-electron reduction products of both 12-molybdophosphate and 12-molybdosilicate are catalytic in nature in the presence of chlorate ions. The six-electron reduction product of 12-molybdophosphate is oxidized by chlorate ions more rapidly than that of 12-molybdosilicate.
