非均质太阳能发电提供了一种利用太阳能生产可再生燃料的有前途的战略。金属杂阴离子光催化剂因其可见光吸收而受到关注;然而，它们也受到光腐蚀的困扰，这限制了它们的长期使用。这种光腐蚀发生在电负性较低的非氧化物离子的光氧化，导致材料晶格的分解。在这个角度来看，我们强调新兴的战略，开发耐用的金属杂阴离子光催化剂。我们专注于模型金属氮氧化物，硫氧化物和卤氧化物光催化剂所采取的方法，提供一个整体的框架。这种分析强调了界面工程，电荷载流子提取，晶体和电子结构在提供光耐久性中发挥的重要作用。我们相信，通过这些方法，可以为可持续的未来开发出持久和吸收可见光的人工光合系统。
Heterogeneous photocatalysis provides a promising strategy to generate renewable fuels by harnessing solar energy. Metal heteroanionic photocatalysts have gained attention for their visible-light absorption; however, they are also plagued by photocorrosion, which limits their long-term use. Such photocorrosion occurs from photooxidation of the less electronegative nonoxide ions, leading to decomposition of the material’s lattice. In this Perspective, we highlight emerging strategies to develop durable metal heteroanionic photocatalysts. We devote attention to the approaches taken for model metal oxynitrides, oxysulfides, and oxyhalide photocatalysts to provide a holistic framework. This analysis emphasizes the vital roles that interface engineering, charge carrier extraction, and crystal and electronic structure play in providing photodurability. We believe that through these approaches, durable and visible-light-absorbing artificial photosynthetic systems can be developed for a sustainable future.
