研究了Bi-P系催化剂物理化学性质(XPS、PAS、TPR及x-光物相分析)和对丙烯氧化脱氢芳构化的催化作用,结果表明丙烯在催化剂表面上为解离吸附,α-H的活化与催化剂金属-氧键强度有关,烯丙基的选择氧化产物取决于其与催化剂间的电子转移能力。
The physicochemical properties (XPS, PAS, TPR and x-ray phase analysis) of Bi-P catalyst and the catalytic oxidation of propylene to dehydroaromatization were investigated. The results showed that propylene was dissociatively adsorbed on the surface of catalyst and α The activation of -H is related to the intensity of the metal-oxygen bond of the catalyst. The selective oxidation of allyl depends on the electron transfer capacity between the catalyst and the catalyst.
