Solar energy-driven semiconductor photocatalysis has gathered increasing interest in the field of energy and environmental applications. However, a vital problem that limits its application is that photocatalysis requires a continuous light source to perform redox reaction. The ability of keeping catalytic activity in the dark has been the ultimate goal for the wide application of photocatalysis. More and more efforts have been paid to develop photocatalysts to perform photocatalytic reactions under both light and dark conditions, which is so called “round-the-clock photocatalytic system” (RTCPS). RTCPS with an ability of energy storage can work well under both daytime and nighttime, which widely used in the removal of heavy metal ion, the degradation of organic pollutant, disinfection and hydrogen generation. The important potential of RTCPS necessitate timely reviews of the recent advances to streamline efforts. Thus, this review aimed to summarize the recent advances in RTCPS, including the mechanism, characterization techniques and applications. Moreover, future challenge and research direction on the mechanistic study, material design and potential applications are also discussed.

太阳能驱动的半导体光催化在能源和环境应用领域中的兴趣日益浓厚。然而，限制其应用的重要问题是光催化需要连续的光源来进行氧化还原反应。在黑暗中保持催化活性的能力一直是光催化广泛应用的最终目标。为了开发在光和暗条件下都可以进行光催化反应的光催化剂，人们进行了越来越多的努力，这就是所谓的“全天候光催化系统”（RTCPS）。具有能量存储能力的RTCPS在白天和晚上都可以很好地工作，广泛用于去除重金属离子，降解有机污染物，消毒和制氢。RTCPS的重要潜力必须及时审查最新进展以简化工作。因此，本综述旨在总结RTCPS的最新进展，包括机理，表征技术和应用。此外，还讨论了机械研究，材料设计和潜在应用方面的未来挑战和研究方向。
