摘　　要：CO_(2)加氢制甲醇是缓解温室效应的重要途径,Cu由于其较高的催化活性和低成本,已成为研究的热点。ZrO_(2)的缺陷位点和表面亲水性使其成为Cu催化剂有效的载体,能够促进CO_(2)的吸附和加氢反应,Cu-ZrO_(2)基催化剂在CO_(2)加氢制甲醇反应中已经展示了优异的催化性能。本研究讨论了Cu-ZrO_(2)催化剂中加氢活性位点的形成机制,表明Cu与ZrO_(2)之间的相互作用及界面处的Cu^(+)/Cu^(α+)位点是甲醇生成的关键。结果表明,新型高效Cu-ZrO_(2)基催化剂的制备方法,如将Cu纳米颗粒封装在MOFs结构中、引入其他助剂(如ZnO、Ga_(2)O_(3))等改善Cu-ZrO_(2)基催化剂的甲醇生成活性和稳定性,并且对Cu-ZrO_(2)基催化剂上CO_(2)加氢制甲醇的微观反应机制和未来的研究方向进行了展望。The hydrogenation of CO_(2)to methanol is a crucial pathway for mitigating the greenhouse effect.Due to its high catalytic activity and low cost,copper(Cu)-based catalysts have become a research focus in this field.ZrO_(2),with its defect sites and surface hydrophilicity,serves as an effective support for Cu cata⁃lysts,facilitating CO_(2)adsorption and hydrogenation.Cu-ZrO_(2)-based catalysts have demonstrated outstanding catalytic performance in CO_(2)hydrogenation to methanol.This study discusses the formation mechanism of hy⁃drogenation active sites in Cu-ZrO_(2)catalysts,revealing that the interaction between Cu and ZrO_(2),along with the Cu^(+)/Cu^(α+)sites at the interface,plays a critical role in methanol synthesis.This paper summarizes ad⁃vanced synthesis strategies for highly efficient Cu-ZrO_(2)-based catalysts,including the encapsulation of Cu nanoparticles within MOF architectures and the incorporation of promoters(e.g.,ZnO,Ga_(2O_(3)))to enhance both methanol synthesis activity and stability.Finally,we provide perspectives on both the microscopic reaction mechanisms of CO_(2)hydrogenation to methanol over Cu-ZrO_(2)-based catalysts and potential future research di⁃rections in this field.
