Research progress of modified electrodes in microbial fuel cell for simultaneously enhancing electricity generation and organic pollutants degradation

摘要:

随着城市化进程的加剧，废水中有机污染物愈显复杂性和难降解性，这些毒害性有机污染物在常规水处理过程中无法得到有效去除，对生态环境和人类健康造成严重威胁。微生物燃料电池（MFC）是一种利用微生物作为催化剂就能实现同步产电及降解有机污染物的绿色能源装置。电极作为MFC的重要组成部分，在提高污染物降解及产电能力方面发挥着至关重要的作用。该文介绍了MFC阳极和阴极改性强化有机污染物降解同步产电的最新研究进展，并对MFC电极材料在废水处理领域的应用做出展望。

Abstract:

As the acceleration of urbanization, the organic pollutants in wastewater have been more complex and persistent. However, these toxic materials could not be effectively removed by conventional wastewater treatment, posing a serious threat to the eco-environment and human health. Microbial fuel cell (MFC), an emerging renewable technology, can directly convert the chemical energy from organic compounds into electricity by microbial catalysis. Electrode design is one of the most important factors in affecting the pollutants degradation and power output capacity. Hence, this review demonstrates the latest developments of organic pollutants removal along with electricity generation by the anode/cathode modification in MFC. Furthermore, the applications of MFC electrode materials in wastewater treatment field are prospected.
