英文摘要	hierarchical multi-walled mno2/polypyrrole/mno2 nanotubes (nt-mpms) were synthesized by a hydrothermal method and were decorated on a carbon cloth anode to promote microbial fuel cell (mfc) power production. compared with bare carbon cloth (ck) anodes, the maximum power density of the mfc with an nt-mpm-decorated anode reaches 32.7 +/- 3 w/cm(3), which is approximately 1.3 times higher than that of the ck, and it exhibits excellent durability. the voltage outputs of the nt-mpm anode mfc decreased by 9.2% after being subjected to more than 90 full discharging-charging cycles. in additionbanode, which facilitated biofilm growth and promoted extracellular electron transfer between the bacteria and the electrode. electrochemical impedance spectroscopy (eis) measurements reveal that nt-mpm anodes lead to a low charge transfer resistance and provide unique active centers that host the bacteria for more efficient electrocatalysis. this study introduces a promising method for the fabrication of high-performance anodes from simple, inexpensive materials.
