摘　　要：采用化学沉积法,以三氯化锑为原料,与Na2S2O3水溶液混和,浸渍二氧化钛氧化铟锡镀膜玻璃电极(ITO/TiO2电极板)制成改良型电极。利用紫外吸收光谱(UV-vis),紫外可见漫反射光谱(DRS),X射线衍射(XRD),扫描电子显微镜(SEM)等方法对样品进行表征。结果表明,Sb2S3沉积效果明显;在波长400 nm至624 nm的可见光范围内,该薄膜有强烈的吸收;循环伏安法的测定确定该电极板具有可见光的响应能力,并且光电转化率为3.4%。A simple method for preparing highly visible photocatalytic activity and stabihty ITO / TiO2/SbS3 electrode plate was developed by a chemical deposition. The electrode was characterized by UV - vis diffuse reflectance spectra （DRS）, X -ray diffraction （XRD）, scanning electron microscope （SEM）. The results showed that antimony sulfide deposits effect was obvious and ITO / TiO2 Sb2S3 film exhibited obvious a strong absorption in the range of wavelengths from 400 to 624 nm. With phosphoric acid buffer solution doing cyclic voltammetry, the plate electrode was detected with the response ability of visible light and IPCE was 3.4 %.
