摘要:

钒磷氧(VPO)是一种重要的复合氧化物,在低链烷烃选择性氧化及氨氧化等反应中表现出优异的催化性能。VPO催化剂组成结构十分复杂,其晶相组成、表面形貌、酸强度等与制备方法有很大的关系,催化剂的制备方法也很大程度上影响着其催化性能。综述了VPO的不同制备方法;并对其主要晶型及特征、晶相之间的转化进行了系统分析,重点探讨了对该催化剂性能强化方法和方式的研究进展,对VPO催化剂的主要应用做了全面的概述,指出了VPO催化剂研究中存在的问题以及今后发展的方向和目标。采用先进的原位表征手段结合理论模拟计算揭示了VPO催化的构效关系,探索了VPO催化剂的新型合成方法,结合现代纳米材料理论,开发了高性能的纳微结构VPO催化剂。

Abstract:

Vanadium phosphorous oxide (VPO) is an important complex oxide with excellent catalytic performances in many reactions such as selective oxidization of light alkanes and ammonium oxidation. Because VPO has quite complicated structures, its phase composition, surface morphology, and acidity are closely related to preparation methods, which affect VPO catalytic performance. Various VPO preparation methods were reviewed to systematically analyze structure, characteristics, and transformation of VPO crystals. Techniques to improve catalytic performance and recent progress were assessed especially. Major application, challenges, and future development of VPO catalysts were further discussed. Advanced in-situ characterization and theoretical simulation were used to explore structure-property relationship and novel synthesis methods of VPO catalyst. With facilitation of modern nanomaterial theory, high performance nanomicro-structured VPO catalyst could be developed.

Key words: mixed oxide, vanadium phosphorous oxide, catalyst, selective oxidation, maleic anhydride, catalysis, chemical reaction
