The urgent need for clean and renewable energy drives the exploration of effective strategies to produce hydrogen. Semiconductor-based photocatalytic hydrogen production technology is one of the ideal processes for direct solar energy conversion and storage that has been widely studied. The development of highly efficient photocatalysts is essential for the cost-effective and large-scale production of hydrogen. CdS-based semiconductor photocatalysts have attracted significant attention due to their unique advantages, including strong visible light absorption capacity, suitable band edge levels and excellent electronic charge transfer. However, unlike TiO2 with good photostability, the intrinsic drawback of photocorrosion of CdS-based semiconductors significantly challenges their durable application in photocatalysis. This review focuses on recent advances in material design and strategies for improving the anti-photocorrosion of CdS-based photocatalysts for applications in photocatalytic overall water splitting to produce hydrogen. Moreover, brief prospective development and challenges in the synthesis of anti-corrosion CdS-based photocatalysts are also presented.
对清洁可再生能源的迫切需求推动了人们探索生产氢气的有效策略。基于半导体的光催化制氢技术是广泛研究的将太阳能直接转化和储存的理想过程之一。开发高效的光催化剂对于实现具有成本效益和大规模生产氢气至关重要。基于 CdS 的半导体光催化剂因其独特的优势而受到广泛关注，包括强可见光吸收能力、合适的能带边缘水平和优异的电子电荷转移。然而，与具有良好光稳定性的 TiO2 不同，基于 CdS 的半导体的光腐蚀内在缺陷严重挑战了它们在光催化中的持久应用。本综述重点介绍了用于光催化整体水分解制氢的基于 CdS 的光催化剂的材料设计和提高抗光腐蚀性的策略方面的最新进展。此外，还简要介绍了合成抗腐蚀 CdS 基光催化剂的发展前景和挑战。
