X-RAY DIFFRACTION STUDY OF BINARY ZINC-OXIDE CATALYSTS

Abstract

The phase composition of binary zinc-containing catalysts was studied by X-ray diffraction. It was found that the formation of two phases of the initial oxides is observed in all the studied catalytic systems. So, samples of the Zr-Zn-O catalytic system consist of phases of zirconium and zinc oxides, samples of the Ce-Zn-O catalytic system consist of phases of cerium and zinc oxides, while samples of the Mg-Zn-O catalytic system consist of phases of magnesium and zinc oxides. It has been established that the crystallinity of binary zinc-containing catalysts varies in the range from 70% to 89%.
