以氧化铋和二乙基二硫代氨基甲酸钠等为原料合成含硫分子前驱体二乙基二硫代氨基甲酸铋，前驱体经过400℃的高温热分解获得Bi2S3产物，并利用x射线粉末衍射分析（XRD）、紫外可见漫反射等分析手段对热分解产物Bi2S3，的晶相和光吸收性质等进行表征。以甲基橙和苯酚为模型研究了Bj2S3光催化性能。结果表明，分子前驱体热分解制得的Bi2S3，可使甲基橙（20mg／L）和苯酚（10mg／L）水溶液的降解率分别达到68％和96％。

Bismuth sulfide was prepared by thermal decomposition of molecule precursor of bismuth dieth- yldithiocarbamate at 400℃. Bismuth sulfide prepared was characterized by X - ray powder diffraction (XRD) and ultraviolet visible diffuse reflection spectrum (UV -vis DRS). The photocatalytic perform- ance of Bi2 S3 prepared was evaluated by degradation of methyl orange and phenol under UV light irradia- tion. The results show that the degradation efficiency for methyl orange (20 mg/L) and phenol ( 10 race/L) over bismuth sulfide oret~ared is 68% and 96%, respectively.
