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.
