摘　　要：挥发性有机化合物(VOCs)是臭氧、二次有机气溶胶生成潜势较高的气态污染物,这类污染物的有效控制是大气复合型污染防治的关键。微生物燃料电池(MFC)技术净化VOCs不仅具有传统生物法绿色、安全、碳排放量低的特点,还能够将污染物中化学能回收为电能,近年来受到广泛关注。结合MFC净化VOCs基本原理,概述了MFC中相际传质、降解反应过程强化的研究思路及进展,介绍了空气电极、光催化技术在新型MFC中的应用。另外,针对产电功率密度及库仑效率受限的瓶颈,对MFC净化VOCs的研究进行了展望,提出改善“微生物-电极”界面电子传递、调控降解菌及产电菌协作关系等重要研究方向。Control of volatile organic compounds(VOCs) with remarkable O3 and secondary organic aerosols formation potentials is crucial for the prevention and treatment of combined air pollution. Microbial fuel cell(MFC) attracts great attentions recently as it has the characteristics of green, safe and low carbon emission,which can also convert chemical energies in VOCs into electricity. Based on the basic mechanism of VOCs degradation in MFC, advances in process intensification of mass transfer and VOCs degradation in MFC were summarized in this review, and the applications of novel air electrodes and photocatalytic technology in MFC systems were introduced. Moreover, the future development of VOCs powered MFC was discussed focused on the bottlenecks of low power density and limited coulombic efficiency. It was suggested that improvements on electron transfer between microorganisms and electrode substrate, and the cooperative relationship between VOCs-degrading bacteria and exoelectrogens are two important research directions.
