Abstract
Photocatalytic technology, which is regarded as a green route to transform solar energy into chemical fuels, plays an important role in the fields of energy and environmental protection. An emerging S-scheme heterojunction with the tightly coupled interface, whose photocatalytic efficiency exceeds those of conventional type II and Z-scheme photocatalysts, has received much attention due to its rapid charge carrier separation and strong redox capacity. This review provides a systematic description of S-scheme heterojunction in the photocatalysis, including its development, reaction mechanisms, preparation, and characterization methods. In addition, S-scheme photocatalysts for CO2 reduction are described in detail by categorizing them as 0D/1D, 0D/2D, 0D/3D, 2D/2D, and 2D/3D. Finally, some defects of S-scheme heterojunctions are pointed out, and the future development of S-scheme heterojunctions is proposed.
光催化技术被视为将太阳能转化为化学燃料的绿色途径，在能源和环境保护领域发挥着重要作用。一种新兴的具有紧密耦合界面的 S 型结构异质结，其光催化效率超过了传统的 II 型和 Z 型光催化剂，因其快速的电荷载流子分离和强大的氧化还原能力而备受关注。本综述系统阐述了光催化中的 S 型梯度异质结，包括其发展、反应机理、制备和表征方法。此外，还详细介绍了用于还原二氧化碳的 S 型光催化剂，将其分为 0D/1D、0D/2D、0D/3D、2D/2D 和 2D/3D。最后，指出了 S 型异质结的一些缺陷，并提出了 S 型异质结的未来发展方向。
