| 中文摘要: |
| 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. |
| 英文摘要: |
| 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. |
