The photoassisted catalytic reaction, conventionally known as photocatalysis, is expanding into the field of energy and environmental applications. It is widely known that the discovery of TiO₂‐assisted photochemical reactions has led to several unique applications, such as degradation of pollutants in water and air, hydrogen production through water splitting, fuel conversion, cancer treatment, antibacterial activity, self‐cleaning glasses, and concrete. These multifaceted applications of this phenomenon can be enriched and expanded further if this process is equipped with more tools and functions. The term “photoassisted” catalytic reactions clearly emphasizes that photons are required to activate the catalyst; this can be transcended even into the dark if electrons are stored in the material for the later use to continue the catalytic reactions in the absence of light. This can be achieved by equipping the photocatalyst with an electron‐storage material to overcome current limitations in photoassisted catalytic reactions. In this context, this article sheds lights on the materials and mechanisms of photocatalytic reactions under light and dark conditions. The manifestation of such systems could be an unparalleled technology in the near future that could influence all spheres of the catalytic sciences.

光和暗条件下光辅助化学反应的材料和机理：能否实现昼夜光催化？

光辅助催化反应，通常称为光催化，正在向能源和环境应用领域扩展。众所周知，TiO ₂的发现辅助的光化学反应导致了多种独特的应用，例如水和空气中污染物的降解，通过水分解产生的氢，燃料转化，癌症治疗，抗菌活性，自清洁玻璃和混凝土。如果此过程配备了更多的工具和功能，则可以丰富和扩展这种现象的这些多方面的应用。术语“光辅助”催化反应明确强调需要光子才能活化催化剂。如果电子存储在材料中，则甚至可以在黑暗中超越，以便以后在没有光的情况下继续进行催化反应。这可以通过为光催化剂配备电子存储材料来克服光辅助催化反应中的电流限制来实现。在此背景下，本文阐明了在黑暗和黑暗条件下光催化反应的材料和机理。这种系统的出现在不久的将来可能是一项无与伦比的技术，可能会影响催化科学的所有领域。
