摘要: 考察了不同组成的V-Sb-O系复合氧化物对丙烷氨氧化的催化活性.用XRD研究了催化剂的结构,利用程序升温方法研究了催化剂中氧的活动性和表面酸碱性,讨论了催化剂体相和表面结构与催化性能间的关系.结果表明,VSbO4和Sb2O4间的协同作用是影响催化活性的重要因素.

Abstract: The ammoxidation of propane was studied over the V/Sb oxide catalysts.The effects of the catalyst composition, structure, reactivity of labile oxygen and surface base-acidity on the catalytic acitivty have been examined by using XRD, TPD-O2, TPRand TPD-NH3. The experiment found that the catalyst with V/Sb=1/5 gave higher activity and selectivity.The results show that the active phase is VSbO4 in the catalyst, the synergistic effects between VSbO4 and Sb2O4 phases have an important influence on the activity of the catalyst.
