摘　　要：将WO3 物种原位引入介孔分子筛SBA 15的骨架内 ,首次得到具有选择氧化活性中心的W SBA 15分子筛 ,并用XRD ,BET ,SEM及TEM等手段进行了表征 .该新型催化剂在环戊烯催化氧化合成戊二醛的反应中表现出优异的催化性能 ,戊二醛的选择性高达 84% ,收率亦达到 79% ,超过所有的负载型含钨催化剂 ,具有极好的应用前景 .W-SBA-15 has been synthesized for the first time by using in situ method and characterized by XRD, BET, SEM, TEM, etc. The as-prepared novel W-SBA-15 shows excellent catalytic performance in the selective oxidation of cyclopentene to glutaraldehyde. The selectivity toward glutaraldehyde was as high as 84% and the yield reached 79%, suggesting its promising potential in industry.
