VSb3W-Al2O3 catalysts for propane ammoxidation were prepared by the conventional slurry method and new slurry method, namely, the reduction-oxidation slurry method. The effect of preparation methods on the physicochemical properties of VSb3W-Al2O3 catalysts were studied by N2 adsorption, XRD, XPS and Raman spectroscopy, and their catalytic performance for the ammoxidation of propane to acrylonitrile were tested. Compared with the VSb3W-Al2O3 catalyst prepared by the conventional slurry method, the VSb3W-Al2O3 catalyst prepared by the reduction-oxidation slurry method exhibited better propane conversion and acrylonitrile selectivity. This is due to that the reduction-oxidation treatment was advantageous for obtaining low valence state vanadium and high valence state antimony to form more rutile SbVO4, which is a vital active phase for propane ammoxidation.
