摘　　要：不饱和醛的选择性加氢作为一类重要的精细化学品加工转化过程,在香精香料、药物食品生产、农产品加工等领域具有广泛应用。但是目前所应用催化剂的反应活性仍有待提高,需对催化剂进行进一步调控。本文总结了提高催化剂加氢选择性的三种策略,包括:改变金属活性位点的电子性质、增强金属活性位点与亲电位点之间的协同作用和利用结构效应来改变催化剂对于C=O键或C=C键的吸附能力和加氢活性。概括了氢源种类、反应溶剂、反应温度和氢气压力等反应条件对催化性能的影响。并归纳了不饱和醛选择性加氢有关的密度泛函理论计算、反应的动力学模型及反应中的构效关系。最后,讨论了不饱和醛选择性加氢催化剂面临的问题和挑战,并提出了可行的解决方案。The selective hydrogenation of unsaturated aldehydes is an important process of fine chemical processing that is widely used in the fields of flavor,medicine and food production,agricultural product processing,and so on.However,the hydrogenation reactivity of current catalysts still needs to be improved and further modulation of catalyst structures is needed.Three design strategies for the selective hydrogenation catalysts are summarized in this paper,modifying the electronic properties of metal active sites,enhancing the synergistic effect between the metal active sites and the electrophilic sites,and utilizing the structural effect to change the adsorption strength and hydrogenation activity of C-O bond or C-C bond.The influences of hydrogen source types,reaction solvents,temperatures and hydrogen pressures on catalytic performance are also summarized.The density functional theory(DFT)calculation,the reaction kinetic model,and the structure-activity relationship of catalysts related to the selective hydrogenation of unsaturated aldehydes are summarized.In the final section,problems,and challenges in the selective hydrogenation of unsaturated aldehydes are discussed,and some feasible solutions are further proposed.
