Electrochemical Reduction of Carbon Monoxide in Aqueous Electrolytes at Gas Diffusion Hydrophobic Electrodes
This paper investigates the influence of the material of the electro-catalyst, the electrode composition, the type and concentration of the electrolyte, the temperature and the potential of the electrode on the electroreduction of carbon monoxide in aqueous electrolytes. The following metal powders were used as electrocatalysts: Co, Ni, Fe, Nb, Pt, W, Cu, Cd, Pb, Zn, and Raney nickel. A large series of tests showed that no organic products were synthesized in the electroysis in the presence of CO on the metals Pt, Nb, Cd, W, Cu, Pb, and Zn. The only product in the whole potential range was hydrogen, derived from the decomposition of the electrolyte. Methane, ethane, and traces of ethylene were obtained on Ni, Co, Fe, and Raney nickel. With respect to the other hydrocarbons the methane content was equal to 95%. Best results were obtained on nickel electrodes.
