摘要
采用微波法制备了 Fe掺杂Bi2S3复合光催化剂(Fe-Bi2S3),用于光芬顿法降解污染物的研究.对Fe-Bi2S3进行了结构、形貌、元素组成、光电化学性能等表征测试,结果表明:Fe-Bi2S3材料呈无定形结构,光响应性能良好,Fe掺杂后的复合物光生载流子分离能力得到明显改善.最优掺杂比的Fe-Bi2S3复合物在30 min内对亚甲基蓝的光芬顿降解效率高达99％,且具有良好的稳定性.最后,提出了 Fe-Bi2S3可能的降解机理.
Abstract
Fe-doped Bi2S3 composite photocatalyst(Fe-Bi2S3)was prepared by microwave method for the degradation of pollutants by PhotoFenton method.The structure,morphology,elemental composition and photoelectrochemical properties of Fe-Bi2S3 have been characterized.The results show that Fe-Bi2S3 has an amorphous structure and good photoresponse performance.The photogenerated carrier separation ability of Fe-Bi2S3 is obviously improved.The PhotoFenton degradation efficiency of methylene blue by 30％Fe-Bi2S3 photocatalyst is up to 99％within 30 min.The as-prepared photocatalyst has good stability.Finally,the possible degradation mechanism of Fe-Bi2S3 was proposed.
