Abstract
The effect of reduction of carbon dioxide by CODH(Carbon Monoxide Dehydrogenase) was compared on glassy carbon and gold working electrodes. In case of gold electrode, the choice of the optimum applied potential is very important since evolution can be mixed with reduction. On the other hand, efficient reduction was observed up to -650 mV vs. NHE on glassy carbon in neutral solution due to the larger overpotential for evolution on glassy carbon surface than that on gold surface. The optimum potential for reduction was found to be vs. NHE. The current efficiency of to CO decreased dramatically at more negative potential according to the activity of enzyme decrease and the hydrogen evolution.
