摘要：

Electrochemical conversion of CO2 into useable aqueous-phase organic molecules was investigated employing a glassy carbon (GC) electrode patterned with nickel nanoparticles (GC-Ni), in a batch electrochemical reactor operating at constant potential, room temperature and atmospheric pressure. The system was found to efficiently convert CO2 into mostly ethanol (91 +/- 1 mol.%), at a very high faradaic efficiency (221 +/- 23% after 8 hours of electrolysis), indicating that the CO2 reduction could most possibly be occurring both electrocatalytically and catalytically.
