摘　　要：传统微生物燃料电池(microbial fuel cells,MFCs)主要由生物阳极与非生物阴极组成,属于半生物燃料电池,存在化学药剂再生困难、需要铂等贵金属催化及成本高等缺陷。生物阴极则利用微生物参与阴极反应克服了这些缺陷。微生物参与MFCs阴极反应,最初在海底沉积物MFCs中被发现。为了提高空气-生物阴极的产电效率,人们进行了以铁、锰等过渡金属氧化物修饰电极材料的研究。在厌/缺氧环境中,生物阴极可将硝酸盐和硫酸盐等作为最终电子受体。对生物阴极研究的深入为MFCs工业化应用开辟了道路,此外,本文在文献综述的基础上提出了铁锰联合修饰生物阴极材料的可能性。Conventional microbial fuel cells （MFCs） consist of biological anodes and abiotic cathodes, which are half-biological fuel cells. The abiotic cathodes usually require a catalyst such as Pt or an electron mediator to enhance power production, thus increasing the cost and lowering the operational sustainability, or even causing secondary pollution. Such disadvantages can be overcome by biocathodes, which firstly found in marine sediment MFCs. The performance of manganese and iron compounds based oxygen reduction catalysts was studied in view of increasing the biological MFCs power output. Moreover, nitrate and sulfate as the terminal electron acceptors can be reduced by anaerobic biocathodes. Biocathodes are promising in MFCs especially after the development of electrode materials, which also-lead the industrialization of MFCs possible. The biocathodic electrodes co-modified by manganese and iron compounds are proposed in this review.
