Resumo

Quantum chemical calculations are performed to determine the heats of reduction with CO of the simplest electrically neutral or electrically charged oxides of nickel (Ni2O2, Ni2O) and copper (Cu2O2, Cu2O). Also calculated are the heats of conversion of neutral or charged copper oxides to active isomers with an O radical. Based on the calculated results, an explanation is proposed for the change in the rates of reduction of nickel and copper nano-oxides with carbon monoxide caused by applying an electrical voltage to the oxides.
