摘要

采用前驱体固相硫化法、共沉淀法、溶剂热法合成了NaInS

光催化剂

通过X射线衍射图谱、紫外-可见漫反射光谱、扫描电镜、X射线光电子能谱等技术对催化剂进行对比研究.研究结果表明

固相硫化所合成的NaInS

光催化剂表面微量的In

可能与NaInS

形成了复合半导体

促进了光生载流子的有效分离

因而提高了光解水产氢的性能

达到了61.68 μmol/(h·g)

同时光稳定性提高的原因可能是因为催化剂具有较小的比表面积.

Abstract

NaInS

catalysts were synthesized by thermal sulfidation of the precursor

coprecipitation and solvothermal. The catalysts were characterized by X-ray diffraction patterns

UV-Vis diffuse reflection spectrum

scanning electron microscopy and X-ray photoelectron spectroscopy. The reason for the high activity of catalyst by thermal sulfidation of the precursor is that NaInS

and a small amount of In

on the surface of the catalyst facilitates forming composite semiconductor to enhance the photocharge separation and heighten the hydrogen evolution rate to 61.68 μmol/(h·g).The stability of the photocatalyst can be obviously improved due to the smaller specific surface area.
