| 摘 要： | 通过高温还原法制得磷化钼(MoP)催化剂,采用X射线衍射和原位x射线光电子能谱对其进行了表征,并考察其催化乙炔选择性加氢性能.结果表明,在650℃经H2还原制得的催化剂中形成了大量的低价态物种MoP,但仍含有大量的高价态Mo和P物种,该催化剂具有加氢活性中心和缺电子中心双重功能,在乙炔选择性加氢反应中,乙炔转化率超过9...

| Abstract: | 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 °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%. |
