当前工业的快速发展导致了严重的能源和环境危机。光催化剂为解决这些问题提供了一种潜在的策略，因为这些材料不仅可以直接将太阳能转化为可利用或可储存的能源，而且可以在太阳光照射下分解有机污染物。然而，上述应用要求光催化剂具有宽吸收范围、长期稳定性、高电荷分离效率和较强的氧化还原能力。不幸的是，单组份光催化剂往往很难同时满足所有这些要求。模拟自然光合作用过程的人工非均相光催化体系克服了单组分光催化剂的缺点，满足了上述要求。在过去的十年里，这样的多任务系统得到了广泛的研究。特别是不含氧化还原对的全固态Z方案光催化体系，在分解水、太阳能电池、污染物降解和二氧化碳转化等方面得到了广泛的应用，在解决当前面临的能源和环境危机方面具有巨大的潜力。因此，本文简要介绍了全固态Z-方案光催化体系的组成、结构、优化及其应用。
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.
