随着经济的快速增长,环境和能源问题日益突出。太阳能作为一种可再生、环保的能源,受到了许多研究人员的关注,最大限度地利用太阳能资源成为未来的研究热点。众所周知,光催化技术可以将太阳能转化为化学能或电能,为环境污染提供解决方案。因此,半导体光催化技术被认为是解决能源危机和环境问题的最环保的技术之一。铋基半导体材料由于合适的能带结构、丰富的种类、无毒性和低成本,在光催化领域受到欢迎。然而,纯Bi基光催化剂存在光激发电子-空穴对复合效率高、量子产率低和光吸收能力有限的问题,导致光催化性能低。为了克服这些限制,人们设计了各种策略,比如金属或非金属掺杂、金属沉积、异质结构建和诱导缺陷生成来提高它们的光催化活性。在这些策略中,元素掺杂或金属沉积被认为是调整铋基材料能带结构和物化性质的有效方法。这个方法拓宽了光响应范围和提高了光催化性能。这篇综述总结了金属掺杂、非金属掺杂、金属和非金属共掺杂以及金属沉积改性铋基材料的最新研究进展。它也探索了它们在光催化降解污染物和重金属离子、氮气还原、二氧化碳还原、光催化抗菌等各个领域的应用。关于金属掺杂,我们将其分为三类:碱金属或碱土金属掺杂、过渡金属掺杂和稀土金属掺杂,并详细介绍了每种掺杂的优缺点。非金属掺杂则被分为卤素掺杂和非卤素掺杂,并重点研究非金属掺杂对铋基材料的影响。此外,我们还纵向比较了每个元素的优点。结合最近的研究进展,简要介绍了结合金属和非金属元素优点的共掺杂。对于金属沉积,我们主要从肖特基势垒和局域表面等离子体共振(LSPR)效应两个方面介绍了对Bi基材料的影响。最后,我们也呈现了金属或非金属改性Bi基光催化剂目前面临的挑战和前景。

关键词：铋基光催化剂金属掺杂非金属掺杂共掺金属沉积电子结构
