摘 要：Biomimetics provides guidance to design and synthesize advanced catalysts for oxygen reduction reaction in microbial fuel cells(MFCs).Herein,jellyfish-inspired Fe clusters on carbon nanotubes connected with CuNC(Fe@CNT@CuNC)were designed and prepared by using zeolitic imidazolate framework(ZIF)-8 precursors to imitate the organic texture and function of *** antibacterial effect of Cu^(+)ions depressed the growth of cathode biofilm to ensure rapid mass *** clusters and CuNC connected by CNTs accelerated the electron transfer from Fe to *** optimization of oxygen adsorption was caused by electron redistribution between sites of Fe and ***-like catalysts achieved a half-wave potential of 0.86 V and onset potential of 0.95 V *** hydrogen electrode(RHE).MFCs gained the maximum power density of 1600 mW·m^(-2) after 500 h *** work provides insights into the special design of advanced catalysts based on bio-inspiration and biomimetics.
