用于废水处理及发电的光电催化微生物燃料电池研究进展

Research Progress of Photocathode Microbial Fuel Cell for Wastewater Treatment and Power Generation

环境污染和能源危机成为当今世界关注的问题,大量的含污废水排入水体中,造成严重的环境污染问题。然而,废水中的大部分能源是可以利用的,光电催化微生物燃料电池(Photo-MFCs)的设计可以实现废水中污染物降解的同时产能的双重收益。本文综述了Photo-MFCs的国内外研究进展,首先介绍了Photo-MFCs的原理、优势及分类,然后重点讨论了光阴极催化剂及光阴极电极的制备,进一步讨论了操作参数对Photo-MFCs性能的影响。最后对Photo-MFCs当前的问题和今后的研究机会进行了展望。

Environmental pollution and energy crisis have become the concern of the world today, A large number of wastewater containing sewage is discharged into the water, causing serious environmental pollution. However, most of the energy in the wastewater is available, and the design of photocathode microbial fuel cells (Photo-MFCs) can achieve the dual benefits of degradation of pollutants in the wastewater and productivity. In this paper, the research progress of Photo-MFCs at home and abroad is summarized. Firstly, the principle, advantages and classification of Photo-MFCs are introduced. Then, the preparation of photocathode catalyst and photoelectrode is discussed emphatically, and the influence of operation parameters on the performance of Photo-MFCs is further discussed. Finally, the current problems and future research opportunities for Photo-MFCs are prospected.
