Mechanochemical synthesis of iron-molybdenum catalyst for formaldehyde synthesis

Abstract

The processes of mechanochemical synthesis of iron-molybdenum catalyst for the partial oxidation of methanol into formaldehyde are studied by powder X-ray diffraction, X-ray structural and synchronous thermal methods, and Mössbauer spectroscopy. The effect of mechanical activation and precursors in use on the formation of iron molybdate Fe₂(MoO₄)₃ phase is revealed. The optimal conditions for its synthesis are determined. The data on catalytic activity of the iron-molybdenum catalysts synthesized from different raw materials are obtained.
