摘要：

CO2 and water vapor was converted into methanol with the catalyst of ZnO-ZrO2 solid solution and the aid of negative corona plasma, which provided synergistic effect when employed together. The yield of methanol was 33.56μmol/h, which was 1.4 times of the sum of those under plasma alone and catalyst alone. The methanol yield increased with the increase of reaction current and steam flow rate, but decreased with the increase of CO2 flow rate. The results of XRD, XPS and CO2-TPD showed that the crystal plane spacing and oxygen vacancies of the catalyst increased under negative corona plasma condition, which enhanced the CO2 adsorption on the catalyst. The CO2-DRIFTs results showed that carboxylate (COO-) was the main intermediate species during the methanol formation. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
