摘　　要：硫化铂族金属催化剂为可提高有机液相加氢反应选择性的高效催化剂,能提高含羰基、羟基和卤素等官能团化合物催化加氢反应的选择性,应用广泛。综述了国内外负载型Pt和Pd等硫化贵金属催化剂的制备方法,包括采用H_2S和Na_2S无机硫化以及Ph_2S和DMSO(二甲基亚砜)等有机硫化剂进行硫化;综述了Pt和Pd硫化贵金属催化剂在有机液相催化加氢体系中的应用;并对硫化Pt族金属催化剂的硫化机理和催化机理进行探讨,展望了硫化贵金属催化剂的应用前景。Noble metal sulfide catalysts are promising catalysts due to their excellent catalytic performance in liquid chemoselective hydrogenation of organic reactants with various reducible functionalities, such as carbonyl, hydroxyl, and halogen. Preparation of supported noble metal sulfides catalysts were re- viewed in this paper, including sulfiding by inorganic H2S, Na2S and organic Ph2S, DMSO. Application of the catalysts in organic synthesis and the catalytic and the sulfiding mechanisms were discussed.
