Abstract:

Recent progress in MoVTeNbO mixed metal oxide catalysts are reviewed with focuses on the preparation procedure on the formation of catalyst active phase，such as the solution pH value，drying and thermal treatment method. The crystal structure study in the latest literatures are summaried and the relationship between catalyst structure and catalytic performance are illustrated. The reaction mechanism of propane selective oxidation to acrylic acid and ammoxidation to acrylonitrile over MoVTeNbO catalyst are discussed. Optimization in preparation conditions，improvement in the diffusion rate of lattice oxygen，regulation in surface acidity and active center initiation are critical to achieve superior catalytic properties．
