简要总结了我们在C=C及C=O双键低温加氢双金属催化剂方面的最新研究成果.首先,我们以环己烯加氢为探针反应,证明了平行使用多种研究手段的重要性,包括单晶表面的基础研究与DFT计算,多晶表面的合成与表征,负载型催化剂的制备与性能测试等.其次,总结了双金属催化剂在其他加氢反应,如丙烯醛C=O双键的选择性加氢,苯的低温加氢,以及乙炔的选择性加氢等反应中的应用.最后,讨论了利用金属碳化物代替贵金属Pt以减少双金属催化剂中Pt用量的可能性. This paper briefly summarizes the latest research results on low temperature hydrogenation bimetallic catalysts with C═C and C═O double bonds.First, we used cyclohexene hydrogenation as a probe reaction, and proved that it is important to use a variety of research methods in parallel Including basic research and DFT calculation of single crystal surface, synthesis and characterization of polycrystalline surface, preparation and performance testing of supported catalysts, etc.Secondly, the effects of bimetallic catalysts on other hydrogenation reactions such as acrolein C = O Selective hydrogenation of double bonds, hydrogenation of benzene at low temperature, selective hydrogenation of acetylene, etc. Finally, the possibility of using metal carbides instead of noble metal Pt to reduce the amount of Pt in the bimetallic catalyst is discussed.
