【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的阴极催化剂的研究重点之一。本文综述了近年来MFC中阴极氧还原催化剂研究进展。得点讨论了贵金属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,所以有望成为MFC阴极Pt基催化剂的替代催化剂。更多还原

【Abstract】 In the MFC,using oxygen as the electron acceptor has many advantages,however,the kinetics of oxygen reduction is slow,which will cause the loss of cathode potential.Thereby enhancing the oxygen reduction activity is one of the focus of MFC research.The progress of cathode catalysts of MFC was reviewed.In particular,the catalytic activity for oxygen reduction reaction(precious metal Pt,transition metal macrocyclic complexes,and non-noble metallic oxide etc.)were focused upon.The transition metal macrocyclic complexes and non-noble metal oxides catalysts displayed good performances and were expected to become the substitutes for the MFC cathode Pt catalysts.更多还原
