摘　　要：近年来半导体光催化作为一种绿色技术在解决环境问题和提供可再生能源方面获得了广泛关注,然而较低的催化效率限制着它的实际应用。合理设计金属氧化物半导体的表/界面结构,是提升光催化剂性能的有效手段。对近年来半导体光催化剂的表/界面结构调控以及构-效关系的研究进行了梳理,介绍了在单一组分体系中利用晶面效应优化光催化性能的可行措施。在此基础上,总结了晶面/界面结构调控在复合光催化剂体系中的应用。最后,总结了该领域面临的挑战与未来的前景。In recent years,semiconductor based photocatalysis,as a green technology,has attracted wide attention in solving environmental problems and providing renewable energy,but the low efficiency still limits its practical application.Rational surface/interface design of metal oxide semiconductor is an effective approach to improve the performance of photocatalysts.Recent progress in the surface/interface structure engineering and structure-activity relationship of semiconductor photocatalysts was systematically reviewed.The feasible measures to optimize the photocatalytic performance by the facet effect in single component were introduced.On this basis,the application of facet/interface engineering strategies in promoting photocatalytic performance of multi-component composite photocatalysts were summarized.Finally,the challenges and opportunities in this field were briefly featured on the basis of its current development.
