Abstract

ZnIn₂S₄, a typical n-type semiconductor, has received intensive attention due to its suitable bandgap, excellent visible light absorption performance, and simple and flexible preparation methods. However, its application is curbed by photo-generated carrier recombination and photo corrosion. Although constructing S-scheme heterojunctions by combining ZnIn₂S₄ with other semiconductors can solve these problems, the photocatalytic activity of S-scheme heterojunctions can be further improved. Therefore, this short review summarizes modification strategies of ZnIn₂S₄-based S-scheme heterojunctions. This article also introduces the concept, design principles, and characterization methods of ZnIn₂S₄-based S-scheme heterojunction. Finally, current challenges and future research focuses related to ZnIn₂S₄-based S-scheme heterojunctions are discussed and summarized, including the utilization of advanced in-situ characterization techniques to further illuminate the photocatalytic mechanism, the DFT-assisted design of catalysts to increase the selectivity of products during photocatalytic CO₂ reduction, and extending the photo-response of ZnIn₂S₄-based S-scheme heterojunction to near-infrared range, etc.

基于 ZnIn2S4 的 S 型异质结研究进展简评：改进策略

ZnIn2S4是一种典型的n型半导体，由于其合适的带隙、优异的可见光吸收性能以及简单灵活的制备方法而备受关注。然而，它的应用受到光生载流子复合和光腐蚀的限制。虽然将ZnIn2S4与其他半导体结合构建S-scheme异质结可以解决这些问题，但S-scheme异质结的光催化活性可以进一步提高。因此，本文对基于znin2s4的S-scheme异质结的修饰策略进行了综述。本文还介绍了基于znin2s4的s型异质结的概念、设计原理和表征方法。最后，对znin2s4 -s型异质结目前面临的挑战和未来的研究重点进行了讨论和总结，包括利用先进的原位表征技术进一步阐明光催化机理，dft辅助设计催化剂以提高光催化CO2还原过程中产物的选择性，以及将znin2s4 -s型异质结的光响应扩展到近红外范围等。
