【Abstract】 The physicochemical properties of Bi-P catalyst system and the mechanism of oxi-dation-dehydrodimerization and aromatization of propylene were investigated by usingXPS,PAS, TPR and X-ray diffraction methods.The results indicated that propylene isdissociatively adsorbed on the surface of the catalyst and the activation of α-hydrogenis related to the strength of metal-oxygen bond in the catalyst. The products of allyloxidation depend on the electron transference between the allylic intermediates andthe catalyst.更多还原
