Abstract: Propylene oxide (PO) is an important organic chemical intermediate. During the synthesis of PO by direct catalytic oxidation, both the selection of catalyst support and the preparation method of catalyst play an important role on the activity of catalyst in addition to the active species on catalyst.In this paper the research progress of the factors which influence catalyst performance is summarized and discussed to provide reference for future work.
