| Abstract
| - Novel thermally stable mesoporous mixed metal Nb−M (M = V, Mo and Sb) oxides were synthesized in thepresence of a nonionic Pluronic P123 surfactant. These oxides displayed promising pore structures and chemicalcompositions for selective oxidative functionalization of propane: high surface areas (up to 200 m2/g), largepore sizes (5−14 nm), and high pore volumes (up to 0.46 cm3/g). The oxidative dehydrogenation of propaneto propylene over mesoporous mixed metal Nb−M oxides employed as a probe reaction suggested that theM component was dispersed as the molecular surface species and also formed a solid solution with NbOx inthe inorganic walls of these mesoporous mixed metal oxides.
