Measurement of the Surface Photovoltage Spectra(SPS) of Mo/Bi series catalysts BixPMo12Oy(x= 2~ 9, y= 43~ 64) showed that with the increase of Bi/P molar ratio, SPS exhibits some changes characteristic of modulated surface band bendings. The phenomena were explained in terms of the basic capacity of vacancies in the scheelite-type structure of the catalysts.

Metallic ions which could form scheelite type structure with Bi and Mo were drawn into MoBiM 2+ M 3+ M +XO multicomponent oxide catalysts. The surface active phase and bulk phase of the catalysts were modified, and the composition and structure of the bulk phase and surface phase were optimized. Several formulations for preparing lattice oxygen catalysts with performance more superior than imported C type catalysts were obtained. The result showed that the modified catalysts can improve...

Metallic ions which could form scheelite type structure with Bi and Mo were drawn into MoBiM 2+ M 3+ M +XO multicomponent oxide catalysts. The surface active phase and bulk phase of the catalysts were modified, and the composition and structure of the bulk phase and surface phase were optimized. Several formulations for preparing lattice oxygen catalysts with performance more superior than imported C type catalysts were obtained. The result showed that the modified catalysts can improve the performance of complex multicomponent oxide catalyst for propylene ammoxidation.

The structure and catalytic properties of Bi-V-Mo-O composite oxide catalysts with different composition for selective oxidation of propane have been studied by using X-ray diffraction (XRD), laser Raman spectroscopy (LRS), temperature-programmed reduction (TPR) and microreactor tests. It has been shown that Bi-V-Mo-O composite oxides formed scheelite-type structure, and the composition and structure of catalysts exert great influences on the catalytic properties for selective oxidation of propane. Increasing Mo content in the composite oxide catalysts, complete oxidation of propane can be suppressed, while the selectivity to acrolein increased to a maximum at Mo/(V+Mo) atomic ratio =0.45. Further increasing the Mo content results in the remarkable decrease of acrolein selectivity. It has been suggested that the catalytic selectivity is correlated to the reactivity of oxygen ions species in the composite oxides.
