Hydrogen production, catalytic organic synthesis, carbon dioxide reduction, environmental purification, and other major fields have all adopted photocatalytic technologies due to their eco-friendliness, ease of use, and reliance on sunlight as the driving force. Photocatalyst is the key component of photocatalytic technology. Thus, it is of utmost importance to produce highly efficient, stable, visible-light-responsive photocatalysts. CIS stands out among other visible-light-response photocatalysts for its advantageous combination of easy synthesis, non-toxicity, high stability, and suitable band structure. In this study, we took a brief glance at the synthesis techniques for CIS after providing a quick introduction to the fundamental semiconductor features, including the crystal and band structures of CIS. Then, we discussed the ways doping, heterojunction creation, p-n heterojunction, type-II heterojunction, and Z-scheme may be used to modify CIS's performance. Subsequently, the applications of CIS towards pollutant degradation, CO reduction, water splitting, and other toxic pollutants remediation are reviewed in detail. Finally, several remaining problems with CIS-based photocatalysts are highlighted, along with future potential for constructing more superior photocatalysts.
由于其环保、易用以及依赖阳光作为驱动力等特点，氢气生产、催化有机合成、二氧化碳还原、环境净化等主要领域都采用了光催化技术。光催化剂是光催化技术的关键组成部分。因此，生产高效、稳定、对可见光响应的光催化剂至关重要。CIS 在其他可见光响应光催化剂中脱颖而出，因为它具有易于合成、无毒、高稳定性和合适的能带结构等优点。在这项研究中，我们在简要介绍了基本半导体特性（包括 CIS 的晶体和能带结构）之后，对 CIS 的合成技术进行了简要的回顾。然后，我们讨论了掺杂、异质结的创建、p-n 异质结、II 型异质结和 Z 型方案等方法如何用于改善 CIS 的性能。随后，详细综述了 CIS 在污染物降解、CO 还原、水分解和其他有毒污染物修复方面的应用。最后，强调了基于 CIS 的光催化剂存在的几个剩余问题，并探讨了构建更优越光催化剂的未来潜力。
