Abstract: Propylene oxide is a widely used chemical raw material.The industrial production methods of propylene oxide are simply introduced,and their advantages and disadvantages are also discussed.The latest research progress in propylene oxide production by propylene epoxidation over Cu-based and Cu-Ag bimetallic catalysts is reviewed in detail.The relationships between the microstructure of catalysts,alkali metal ions promoters as well as the synergetic effects of bimetallic catalysts and the catalytic performances of propylene epoxidation are introduced emphatically.The reaction mechanism of propylene epoxidation is also discussed.Finally,the prospects in this field are presented.
