摘要：

A MoP catalyst was prepared by high temperature hydrogen reduction. Its properties were investigated by X-ray diffraction and in-situ X-ray photoelectron spectroscopy. It was used for the selective catalytic hydrogenation of acetylene. The results indicated that MoP is formed by hydrogen reduction at 650 degrees C. The prepared MoP catalyst contained high valence molybdenum and phosphorus species. The catalyst is a bifunctional catalyst, which includes a hydrogenation center and an electron-deficient center. Ethylene selectivity can exceed 73% when the acetylene conversion is higher than 99%.
