With global warming and the depletion of fossil resources, our fossil fuel-dependent society is expected to shift to one that instead uses hydrogen (H) as a clean and renewable energy. To realize this, the photocatalytic water-splitting reaction, which produces H from water and solar energy through photocatalysis, has attracted much attention. However, for practical use, the functionality of water-splitting photocatalysts must be further improved to efficiently absorb visible (Vis) light, which accounts for the majority of sunlight. Considering the mechanism of water-splitting photocatalysis, researchers in the various fields must be employed in this type of study to achieve this. However, for researchers in fields other than catalytic chemistry, ceramic (semiconductor) materials chemistry, and electrochemistry to participate in this field, new reviews that summarize previous reports on water-splitting photocatalysis seem to be needed. Therefore, in this review, we summarize recent studies on the development and functionalization of Vis-light-driven water-splitting photocatalysts. Through this summary, we aim to share current technology and future challenges with readers in the various fields and help expedite the practical application of Vis-light-driven water-splitting photocatalysts.
随着全球变暖以及化石资源的枯竭，我们这个依赖化石燃料的社会有望转向一个使用氢气（H）作为清洁可再生能源的社会。为实现这一目标，通过光催化从水和太阳能中产生氢气的光催化水分解反应备受关注。然而，为了实际应用，必须进一步提高水分解光催化剂的功能，以有效吸收占阳光大部分的可见光（Vis）。考虑到水分解光催化的机制，必须有各个领域的研究人员参与此类研究才能实现这一目标。然而，对于催化化学、陶瓷（半导体）材料化学和电化学以外领域的研究人员来说，要参与这个领域，似乎需要新的综述来总结以往关于水分解光催化的报道。因此，在本综述中，我们总结了可见光驱动的水分解光催化剂的开发和功能化方面的最新研究。通过这一总结，我们旨在与各个领域的读者分享当前技术和未来挑战，并帮助加快可见光驱动的水分解光催化剂的实际应用。
