To solve resource, energy, and environmental issues, development of sustainable clean energy system is strongly required. In recent years, hydrogen has been paid much attention to as a clean energy. Solar hydrogen production by water splitting using a photocatalyst as artificial photosynthesis is a promising method to solve these issues. Efficient utilization of visible light comprised of solar light is essential for practical use. Three strategies, i.e., doping, control of valence band, and formation of solid solution are often utilized as the useful methods to develop visible light responsive photocatalysts. This minireview introduces the recent work on visible-light-driven photocatalysts developed by substitution with metal cations of those strategies.

解决资源、能源和环境问题，迫切需要发展可持续的清洁能源体系。近年来，氢作为一种清洁能源备受关注。使用光催化剂作为人工光合作用，通过水分解产生太阳能是解决这些问题的一种很有前途的方法。有效利用由太阳光组成的可见光对于实际应用是必不可少的。三种策略，即掺杂、价带控制和固溶体形成，常被用作开发可见光响应光催化剂的有用方法。这篇小综述介绍了最近通过用这些策略的金属阳离子取代而开发的可见光驱动光催化剂的工作。
