摘　　要：介绍了近年来丙烷氧化脱氢催化技术的最新研究进展,针对其中应用最广泛的钒基介孔催化剂,对其反应机理、载体性能和制备方法进行了综述,并比较了不同催化体系的丙烷氧化脱氢性能,提出了改善钒基介孔催化剂催化活性与选择性的途径。通过比较已经报道的同类研究结果,着重阐述了载体的孔结构对于氧化脱氢过程的影响,比表面积和孔径的优化对于提高催化剂的活性组分分散度以及活性位的数量效果明显。今后研究应着重提高催化剂孔道结构在高温下的稳定性以及使用寿命。The mesoporous catalytic materials for oxidative dehydrogenation （ODH） of propane to propene,especially supported vanadia mesoporous catalysts,were reviewed. The mechanism of ODH and the influence of the properties of supports and preparation methods one activity and selectivity were introduced,and the way to improve catalytic performance was discussed. The influence of pore structure on ODH process was analyzed. Dispersion of catalyst active components and number of active sites could be enhanced by optimizing pore diameter and specific surface area. The stability of catalyst pore structure at a high temperature and service life should be the focus in future research.
