英文摘要: A novel and efficient way for conversion of CO2 and H2O into ethanol over a commercial Cu/ZnO/Al2O3 catalyst with the assistance of negative corona discharge plasma was presented in this work. The low-temperature production rate and selectivity of ethanol were effectively enhanced by combining catalyst with plasma. The production rate of ethanol increased with increasing of input power and water vapor content, while decreased with the increase of flow rate of CO2. XRD and XPS results revealed that metallic copper was partly or completely oxidized after reaction and FTIR results uncovered that on the oxidized copper CO2 adsorbed as carboxylate (COO−) which finally hydrogenated to ethanol. The synergistic effect of partly oxidized copper combined with plasma could promote the dissociation of methanol to form ethanol, which resulted in the high selectivity of ethanol. © 2017
