摘要: 采用一步水热法制备了一系列的ZnIn2S4/ZnS复合光催化剂。对合成样品进行了X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、高分辨透射电子显微镜(HRTEM)、紫外-可见漫反射光谱(DRS)等表征。结果表明,ZnIn2S4纳米片与ZnS纳米粒子形成了复合异质结构;与ZnIn2S4复合,提高了ZnS的光吸收能力。在可见光激发下,测试了光催化剂的分解水制氢性能。ZnIn2S4ZnS的物质的量的比为7∶3时,ZnIn2S4/ZnS复合光催化剂(ZZ-3)的光催化活性最高,产氢速率为61255 μmol·h·g-1。光致发光(PL)光谱和电化学阻抗(EIS)谱表明,在ZnIn2S4ZnS的异质结界面上,光生电子-空穴对实现了有效分离,从而提高了光催化产氢性能。

Abstract: Facile one-step hydrothermal method was used to prepareZnIn2S4/ZnS composite photocatalysts.The products werecharacterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy (TEM), high-resolution transmission electron microscope (HRTEM) and UV-vis diffuse reflectance spectroscopy (DRS).The results proved that ZnIn2S4/ZnS heterojunctionformed successfully and could absorb visible light. The photocatalytic hydrogen production performance of ZnIn2S4/ZnS composites were studied under the excitation of visible light. The composite photocatalyst with the molar ratio of n(ZnIn2S4)∶n(ZnS) of 7∶3 (ZZ-3) showed thehighest activity for hydrogen evolution (61255 μmol·h·g-1).The photoluminescence (PL) and the EIS spectrarevealed that effective separation of the photogenerated electron-hole pairsachievedat the interface of ZnIn2S4 and ZnS, leading to the enhancement of the photocatalytic property.

Key words: ZnIn2S4; zinc sulfide; hydrogen evolution from water splitting; photocatalysis
