Epoxides are among the most important essential building blocks with wide downstream applications in the chemical industry. In this context, rational design of cost-effective catalysts is critical to achieve high atom efficiency during epoxidation processes. Therefore, in this perspective, recent research progress on heterogeneous W and Nb nanocatalysts for facile liquid-phase epoxidation will be critically reviewed in terms of catalyst synthesis, surface characterization and structure–function relationship. Furthermore, plausible mechanisms for liquid-phase epoxidation of ethylene, propylene, hexene, octene and other light olefins, as well as deactivation mechanism of W and Nb catalysts will be systematically discussed with the aim to provide insights into fundamental understanding on novel epoxidation chemistry and improving activity, selectivity, and stability nanocatalytic materials.

W和Nb纳米催化剂上轻烯烃的液相环氧化

环氧化合物是化学工业中最重要的重要组成部分，具有广泛的下游应用。在这种情况下，合理设计具有成本效益的催化剂对于在环氧化过程中实现高原子效率至关重要。因此，从这个角度出发，将从催化剂合成，表面表征和结构-功能关系的角度，对近年来用于液相液相环氧化的多相W和Nb纳米催化剂的最新研究进展进行严格的综述。此外，将系统地讨论乙烯，丙烯，己烯，辛烯和其他轻质烯烃的液相环氧化的合理机理，以及W和Nb催化剂的失活机理，目的是为对新型环氧化化学和化学的基本认识提供见解。改善活动，
