Abstract

A sustainable pathway to green hydrogen generation, the design and synthesis of targeted photocatalysts based on semiconductors or other organic/inorganic materials has emerged as a promising approach for efficient hydrogen production under light irradiation. In this paper, wollastonite-ZnIn₂S₄ composite photocatalysts (ZIS-W) were successfully prepared by the chemical deposition method with wollastonite as the carrier. The hydrogen evolution reaction from water under simulated sunlight irradiation and the enhancement mechanism of ZIS-W were investigated. The results showed that ZIS-W exhibits favorable photocatalytic hydrogen evolution performance and stability, and the photocatalytic hydrogen evolution efficiency of ZIS-W was 4.94 mmol h⁻¹ g⁻¹, which was 1.44 times higher than that of pure ZnIn₂S₄. The unique crystal structure of wollastonite provides favorable conditions for the growth of ZnIn₂S₄ and effectively enhances the dispersion and stability of ZnIn₂S₄. The recombination of photogenerated electron-hole pairs was effectively suppressed while the specific surface area was increased. This study provided a facile synthesis method for preparing photocatalysts with highly efficient hydrogen generation.

精心设计的硅灰石- znin2s4复合光催化剂用于高效制氢

设计和合成基于半导体或其他有机/无机材料的目标光催化剂是实现绿色制氢的可持续途径，这是一种在光照射下高效制氢的有前途的方法。以硅灰石为载体，采用化学沉积法制备了硅灰石- znin2s4复合光催化剂（ZIS-W）。研究了模拟日光照射下水的析氢反应及ZIS-W的增强机理。结果表明，ZIS-W具有良好的光催化析氢性能和稳定性，其光催化析氢效率为4.94 mmol h−1 g−1，是纯ZnIn2S4的1.44倍。硅灰石独特的晶体结构为ZnIn2S4的生长提供了有利条件，有效提高了ZnIn2S4的分散性和稳定性。在增加比表面积的同时，有效地抑制了光生电子-空穴对的复合。本研究为制备高效产氢光催化剂提供了一种简便的合成方法。
