Synthesis of Molybdenum and Vanadium-Based Mixed Oxide Catalysts with Metastable Structure: Easy Access to the MoVNbTe(Sb)O<i>_x</i> Catalytically Active Structure Using Reductant and Oxoacid

Abstract

This work presents a simple synthesis route for MoVNbTe(Sb)Ox with the metastable structure that is catalytically active for the selective oxidation of light alkanes. The addition of an oxoacid to the partially reduced raw material mixture assisted in the formation of the active structure around 600 °C in an O2-excluded atmosphere. This simple synthesis using a reductant and oxoacid is remarkable since it allows a combinatorial approach to diversify Mo- and V-based mixed oxides such as catalytic materials.
