The current rapid industrial development causes the serious energy and environmental crises. Photocatalyts provide a potential strategy to solve these problems because these materials not only can directly convert solar energy into usable or storable energy resources but also can decompose organic pollutants under solar-light irradiation. However, the aforementioned applications require photocatalysts with a wide absorption range, long-term stability, high charge-separation efficiency and strong redox ability. Unfortunately, it is often difficult for a single-component photocatalyst to simultaneously fulfill all these requirements. The artificial heterogeneous Z-scheme photocatalytic systems, mimicking the natural photosynthesis process, overcome the drawbacks of single-component photocatalysts and satisfy those aforementioned requirements. Such multi-task systems have been extensively investigated in the past decade. Especially, the all-solid-state Z-scheme photocatalytic systems without redox pair have been widely used in the water splitting, solar cells, degradation of pollutants and CO2 conversion, which have a huge potential to solve the current energy and environmental crises facing the modern industrial development. Thus, this review gives a concise overview of the all-solid-state Z-scheme photocatalytic systems, including their composition, construction, optimization and applications.
当前快速的工业发展导致了严重的能源和环境危机。光催化剂提供了一种潜在的解决这些问题的策略，因为这些材料不仅可以直接将太阳能转化为可用或可储存的能源，还可以在太阳光照射下分解有机污染物。然而，上述应用需要具有宽吸收范围、长期稳定性、高电荷分离效率和强氧化还原能力的光催化剂。不幸的是，通常很难有一种单一成分的光催化剂同时满足所有这些要求。人工异质 Z 型光催化系统，模拟了自然光合作用过程，克服了单一成分光催化剂的缺点，并满足了上述要求。在过去的十年中，这种多任务系统得到了广泛的研究。特别是，没有氧化还原对的全固态 Z 型光催化系统已广泛应用于水分解、太阳能电池、污染物降解和 CO2 转化，它们具有巨大的潜力来解决现代工业发展所面临的当前能源和环境危机。因此，本综述简要概述了全固态 Z 型光催化系统，包括其组成、构建、优化和应用。
