简述了负载型贵金属催化剂的种类，指出负载型双贵金属催化剂比单贵金属催化剂在催化加氢体系中具有更高的催化活性、选择性和稳定性。针对在催化加氢反应中应用较多的负载型双贵金属Pd-Pt、Pd-Ru、Pd-Rh、Pd-Ag、Pd-Au和Pt-Ru催化剂分别进行了简要介绍与评价。结果表明，这些负载型双贵金属催化剂在各种类型加氢反应中均表现出优异的催化性能。

The types of supported precious metal catalysts are briefly described,and it is pointed out that supported binary precious metals catalysts show higher catalytic activity,selectivity,and stability than single precious metal catalysts in catalytic hydrogenation system.The supported binary precious metals catalysts that are mostly applied in catalytic hydrogenation reactions are introduced and evaluated,such as palladium-platinum,palladium-ruthenium,palladium-rhodium,palladium-silver,palladium-gold,and platinum-ruthenium catalysts.It is shown that these supported binary precious metals catalysts exhibit excellent catalytic performance in various types of hydrogenation reactions.
