Semiconductor photocatalysts have attracted increased attention due to their great potential for solving energy and environmental problems. The formation of Z-scheme photocatalytic systems that mimic natural photosynthesis is a promising strategy to improve photocatalytic activity that is superior to single component photocatalysts. The connection between photosystem I (PS I) and photosystem II (PS II) are crucial for constructing efficient Z-scheme photocatalytic systems using two photocatalysts (PS I and PS II). The present review concisely summarizes and highlights recent state-of-the-art accomplishments of Z-scheme photocatalytic systems with diverse connection modes, including i) with shuttle redox mediators, ii) without electron mediators, and iii) with solid-state electron mediators, which effectively increase visible-light absorption, promote the separation and transportation of photoinduced charge carriers, and thus enhance the photocatalytic efficiency. The challenges and prospects for future development of Z-scheme photocatalytic systems are also presented.
半导体光催化剂因其在解决能源和环境问题方面的巨大潜力而受到越来越多的关注。模仿自然光合作用的Z型光催化系统的形成是提高光催化活性的一种有前途的策略，其光催化活性优于单组分光催化剂。光系统I（PS I）和光系统II（PS II）之间的连接对于使用两种光催化剂（PS I和PS II）构建高效的Z型光催化系统至关重要。本综述简要总结并突出了具有不同连接模式的Z型光催化系统的最新研究成果，包括：i）使用穿梭氧化还原介质；ii）不使用电子介质；iii）使用固态电子介质，这些连接模式有效地增加了可见光吸收，促进了光生电荷载流子的分离和传输，从而提高了光催化效率。同时还介绍了Z型光催化系统未来发展面临的挑战和前景。
