摘　　要：叙述了高活性PtMo2C/Al2O3催化剂的制备、性能和在水气位移反应中的应用。由于制备出的PtMo2C/Al2O3催化剂中,其铂离子呈几个纳米分散态显微结构,分布十分均匀,它比传统的催化剂如CuZn/Al2O3、Pt/C、Pt/Al2O3和PtCeO2等的催化活性高,选择性好,WGS速率高,反应温度低。High-activity PtMo2C/Al2O3 catalyst in WGS reaction was reviewed,as well as its preparation and preformance.Nano platinum particles of PtMo2C/Al2 O3 catalyst were uniform distribution with several nanometers in microstructure,and therefore,they showed high activity and selectivity in WGS reaction with high reaction rate and low temperature,comparing with condtional catalysts,such as CuZn/Al2O3,Pt/C,Pt/Al2O3 and PtCeO2 etc.
