摘 要:本文对金属磷化物的制备方法及催化活性进行了综述。金属磷化物常采用金属化合物和磷酸盐在氢气中还原进行制备,但这种方法的缺点是还原温度太高。磷化氢还原,亚磷酸盐与次磷酸盐以及磷酸盐的等离子体还原都可在低温下进行,制备出的金属磷化物颗粒半径小且有较高的催化活性。金属磷化物具有优异的加氢脱硫(HDS)、加氢脱氮(HDN)活性和稳定性成为催化材料方面研究的热点。另外,贵金属和双金属磷化物催化剂在加氢反应中也表现出了较高的活性和选择性。The preparation methods and catalytic activity of metal phosphide are reviewed in this paper. Metal phosphide is usually prepared by reduction of metal compounds and phosphate in hydrogen, but the disadvantage of this method is that the reduction temperature is too high. The reduction of phosphine, the reduction of phosphite and hypophosphite, and the plasma reduction of phosphate can be carried out at low temperature. The prepared metal phosphide particles have small radius and high catalytic activity. Metal phosphide with excellent hydrodesulfurization( HDS) and hydrodenitrogenation( HDN) activity and stability has become a research hotspot in catalytic materials. In addition, noble metal and bimetallic phosphide catalysts also exhibit high activity and selectivity in hydrogenation.
