摘要

摘要: 以不同载量的MnO₂/rGO和Pt/C修饰阴极电极构建了生物阴极型双室微生物燃料电池（MFC），考察了不同阴极催化剂修饰MFC对其产电性能以及老龄垃圾渗滤液主要污染物去除效果的影响。结果表明，以MnO₂/rGO修饰MFC阴极电极材料，能显著提高MFC产电性能及对老龄垃圾渗滤液中污染物去除效果；输出电压为372 mV，功率密度为194 mW/m³（是未经催化剂修饰MFC的两倍），内阻为264Ω，化学需氧量（COD）和氨氮（NH₃-N）去除率分别为58.68%和76.64%。当MnO₂/rGO载量为1.0 mg/cm²时，MFC性能与负载Pt/C的MFC性能接近，但构建成本却明显降低。

Abstract: Bio-cathode microbial fuel cells (MFCs) were modified with MnO₂/rGO and Pt/C; the effects of cathode catalyst modification on the performance of microbial fuel cells in electricity production and aged landfill leachate treatment were investigated. The results show that the MFC modified with MnO₂/rGO can significantly enhance the electricity production and the removal of contaminants. The MFC modified with 1.0 mg/cm² MnO₂/rGO exhibits a harvest voltage of 372 mV, power density of 194 mW/m³, chemical oxygen demand removal rate of 58.68%, and ammonia removal rate of 76.64%; such a performance is similar to that modified with Pt/C, but the cost is greatly reduced.
