X-ray studies of binary vanadium-containing catalysts were carried out. The results of the investigations showed that in the W–V–O system three phases are formed, two modifications of WO3 and one V2O5. Based on the analysis of diffraction patterns, it was found that in all samples of the Sn–V–O system are observed the phases of SnO2 and V2O5 oxides. It is found that in the Mo–V–O system, in addition to MoO3 and V2O5
oxides, various ternary compounds and solid solutions with the general formula MomVnOp are formed
