Deposition of iron, cobalt, and nickel phosphides on the surface of highly porous silica

Abstract

The sol-gel method was used to obtain materials with deposited cobalt and nickel phosphides of the general formula Me2P and iron phosphide on highly porous silica ( S sp 811 m2/g). The advantage of the methods for obtaining materials considered in the work is the absence of the need to use structure-forming substances, such as surfactants. The properties of materials obtained by different methods were compared. For all materials, it was found that the proportion of metal is 4.5-4.7 wt.% of the material.
