摘要: 在微生物燃料电池(MFC)中,以氧为电子受体具有很多优点,但氧阴极还原的反应动力学慢,会造成阴极电势的损失。 因此,提高阴极对氧还原的电催化活性和降低催化剂的价格是MFC非生物阴极催化剂的研究重点之一。 本文综述了近年来MFC中非生物阴极氧还原催化剂的研究进展。 重点讨论了贵金属Pt、过渡金属大环化合物以及金属氧化物催化剂对氧还原的电催化活性。 其中,非贵金属氧化物及过渡金属大环化合物催化剂具有良好的性能,而且价格低廉,有望成为MFC非生物阴极Pt基催化剂的替代催化剂。

Abstract: Using oxygen as the electron acceptor in microbial fuel cells(MFC) has many advantages. However, the kinetics of oxygen reduction is rather slow, which may cause the loss of cathode potential. Thereby enhancing the oxygen reduction activity is one of the main focuses of MFC research. The progress of abiotic cathode catalysts of MFC is reviewed in this paper, while the catalytic activities of precious metal Pt, transition metal macrocyclic complexes, and non-noble metallic oxide for oxygen reduction are particularly focused. The transition metal macrocyclic complexes and non-noble metal oxides catalysts display good performances and are expected to become the substitutes for the MFC abiotic cathode Pt catalysts.

Key words: microbial fuel cell, cathode catalysts, oxygen reduction
