In this communication, we report a binder-free oxygen reduction cathode for microbial fuel cells. The binder-free cathode is prepared by growth of nitrogen-doped carbon nanofibers (NCNFs) on stainless steel mesh (SSM) via simple pyrolysis of pyridine. The interaction force between NCNFs and SSM surface is very strong which is able to tolerate water flush. The NCNFs/SSM cathode shows high and stable electrocatalytic activity for oxygen reduction reaction, which is comparable to that of Pt/SSM and ferricyanide cathode. This study proposes a promising low-cost binder-free cathode for microbial fuel cells.
在本通讯中，我们报告了一种用于微生物燃料电池的无粘结剂氧还原阴极。无粘结剂阴极是通过在不锈钢网上简单热解吡啶来生长氮掺杂碳纳米纤维（NCNFs）制备的。NCNFs 和 SSM 表面之间的相互作用力非常强，能够耐受水冲洗。NCNFs/SSM 阴极对氧还原反应表现出高且稳定的电催化活性，可与 Pt/SSM 和铁氰化物阴极相媲美。本研究为微生物燃料电池提出了一种有前途的低成本无粘结剂阴极。
