A series of V-Cr/SBA-15 catalysts with different V and Cr contents were prepared by the incipient wetness impregnation method. The structure of the catalysts was characterized by XRD,BET and TPR technique.

• 以介孔分子筛SBA-15为载体,V和Cr为活性组分,采用浸渍法制备了不同V和Cr质量分数的V-Cr/SBA-15催化剂,研究了其对二氧化碳氧化丙烷制丙烯反应的催化性能,采用XRD、BET、TPR等分析测试技术对催化剂的结构进行了表征。
