Catalysis The hydrogenation of carbon dioxide is a key step in the industrial production of methanol. Catalysts made from copper (Cu) and zinc oxide (ZnO) on alumina supports are often used. However, the actual active sites for this reaction—Zn-Cu bimetallic sites or ZnO-Cu interfacial sites—are debated. Kattel et al. studied model catalysts and found that ZnCu became as active as ZnO/Cu only after surface oxidation formed ZnO. Theoretical studies favor a formate intermediate pathway at a ZnO-Cu interface active site. Science , this issue p. [1296][1] [1]: /lookup/doi/10.1126/science.aal3573

金属氧化物协同作用

催化 二氧化碳的加氢是甲醇工业生产的关键步骤。通常使用氧化铝载体上的铜 (Cu) 和氧化锌 (ZnO) 制成的催化剂。然而，该反应的实际活性位点——Zn-Cu 双金属位点或 ZnO-Cu 界面位点——存在争议。卡特尔等人。研究了模型催化剂，发现只有在表面氧化形成 ZnO 后，ZnCu 才变得与 ZnO/Cu 一样活跃。理论研究支持 ZnO-Cu 界面活性位点处的甲酸盐中间途径。科学，这个问题 p。[1296][1][1]：/lookup/doi/10.1126/science.aal3573
