摘要：

The electrochemical reduction of CCl2F2 (CFC-12) was carried out at Pd, An, Cu and Ag cathodes, which were chemically deposited on Nafion 117 (H+ form) membrane; the main electrolysis product at -1.0 V vs. Ag/AgCl at Au, Pd and Cu was CH4, with current efficiencies (CE) of 14, 15 and 47% respectively, while at Ag cathode, in addition to CH4, a considerable quantity of CH2F2 (CE 60%) was also detected, which might be used as a new technology refrigerant.
