The novel thermally stable mesoporous multicomponent MNbOx (M - V, Mo, and Te) mixed metal oxides were successfully synthesized by evaporationinduced self-assembly (EISA) employing niobium oxide as a major structural component. The formation of nanocrystalline M1 phase as part of the ordered mesoporous structure was investigated. These mixed metal oxide phases displayed good thermal stability (up to 400 °C), large pore sizes (up to 14 nm), high surface areas (up to 230 m2/g) and flexible inorganic wall compositions. Thermally stable mesoporous Nb2O5 supported metal M/Nb (M - MoV-TeNb) oxides were obtained by incipient-wetness impregnation (IWI) technique. The comparison between mesoporous bulk mixed and supported mixed metal oxides (MNbOx and M/Nb) were addressed. The catalytic roles of the constituent metal oxides were investigated in oxidative dehydrogenation (ODH) of propane. The methods described in this paper represent promising synthetic approaches for the design of novel catalytic mixed metal oxides.
