relieving mass transport constraints. The proposed reaction mechanism was comparable to that presented in Scheme 1a.
3 Electroreduction of Carbon Dioxide to Carbon Monoxide
CO is another two-electron reduction product from CO 2 and is an important material
in C1 chemistry. For example, a mixture of H 2 and CO, known as synthesis gas, can
be used as a precursor for the production of methanol (CH 3 OH) and hydrocarbons.
