We claim:
1. A method of producing methanol from carbon dioxide,
comprising:
electrolyzing a solution of carbon dioxide in an aqueous solvent having an electrolyte therein and utilizing a cathode which comprises molybdenum to produce methanol.

2. A method as set forth in claim 1, wherein the pH of the solution falls within the range from about 0 to about 7.
3. A method as set forth in claim 1, wherein the cathode is controlled to have a voltage from about -0.5 V to about -1.1 V relative to SCE.
