摘　　要：选择性加氢在化学工业中占有十分重要的地位,在精细化学品和石油化工产品生产、药物合成以及农用化学品的合成中都有重要应用。Pd基催化剂由于其独特的电子结构和吸附活化氢及不饱和底物的能力,在选择性加氢反应中得到了广泛的应用。本文综述了Pd基催化剂的尺寸、组成、表面和界面结构对其性能的影响,并介绍了Pd基催化剂在炔、醛、酮和硝基芳烃选择性加氢反应中的研究进展。Selective hydrogenation plays an important role in chemical industry,and has important applications in the production of fine chemicals and petrochemical products,pharmaceuticals and the synthesis of agricultural chemicals.Palladium-based catalysts have been widely used in selective hydrogenation because of their unique electronic structure and ability to adsorb and activate hydrogen and unsaturated substrates.The effects of the size,composition,surface and interfacial structure of palladium-based catalysts on their properties were reviewed.The research progress on palladium-based catalysts in selective hydrogenation of alkynes,aldehydes,ketones and nitroaromatics was also introduced.
