Photocatalytic hydrogen evolution using inexhaustible clean solar energy is considered as a promising strategy. In order to build an efficient photocatalytic hydrogen production system to satisfy the demands of practical applications, it is of great significance to design photocatalysts that offer high activity, low cost, and high stability. Herein, a series of cheap CdS/Ni(OH) composite photocatalysts were designed and synthesized using the hydrothermal method. The introduction of a Ni(OH) cocatalyst multiplied the reactive active site of cadmium sulfide and promoted the transfer of photoinduced electrons in a semiconductor. Therefore, CdS/Ni(OH) composites demonstrate significantly better photocatalytic performance, and the hydrogen production rate of an optimal CdS/5%Ni(OH) composite is 6.9 times higher than that of blank CdS. Furthermore, the stability test also showed that CdS/Ni(OH) had good stability. This study aims to serve as a rewarding reference for the development of high-performance composite photocatalysts.
利用取之不尽的清洁太阳能进行光催化析氢被认为是一种很有前景的策略。为了构建一个高效的光催化制氢系统以满足实际应用的需求，设计具有高活性、低成本和高稳定性的光催化剂具有重要意义。在此，采用水热法设计并合成了一系列廉价的CdS/Ni(OH)复合光催化剂。引入Ni(OH)助催化剂使硫化镉的反应活性位点成倍增加，并促进了半导体中光生电子的转移。因此，CdS/Ni(OH)复合材料表现出明显更好的光催化性能，最佳的CdS/5%Ni(OH)复合材料的产氢速率比空白CdS高6.9倍。此外，稳定性测试还表明CdS/Ni(OH)具有良好的稳定性。本研究旨在为高性能复合光催化剂的开发提供有价值的参考。
