MoS_2/ZnIn_2S_4 composites with MoS_2 anchored on the surface of ZnIn_2S_4 microspheres were synthesized by a two-step hydrothermal process. The obtained samples were characterized by X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, ultraviolet–visible diffuse reflectance absorption spectroscopy, nitrogen adsorption– desorption measurements, photoluminescence spectroscopy, and photoelectr...

开发高效、稳定的半导体光催化材料是太阳能光催化制氢领域的研究热点,ZnIn2S4因其合适的能隙、带边电势位置以及稳定、低毒等优点而受到广泛关注.但在实际应用中,单纯的ZnIn2S4光催化制氢活性仍较低,主要原因是ZnIn2S4受激产生光生电子-空穴对后,载流子的传输、分离效果不理想,易在体相或表面复合;再者是单一的ZnIn2S4表面缺少催化反应产氢的活性位点.为提高催化活性,通常在催化剂的表面负载一定量的贵金属作为助催化剂,但由于贵金属成本高和稀缺性,限制了其实际的应用.因此,开发低成本、储量丰富、高效的非贵金属助催化剂来增强ZnIn2S4的光催化制氢活性具有显著意义.最近研究表明,具有层状结构...
