为提高微生物燃料电池（MFC）的产电性能，采用热解具有氧还原反应活性的Cu（II）基金属有机骨架（MOF; Cu-bipy-BTC，bipy = 2，2 ′-bipyridine，BTC = 1，3，5-tricarboxylate）制备的Cu，N掺杂的碳基材料作为催化剂，对MFC阴极进行改性，以提高其氧还原反应（ORR）活性。M0 F-800（在800 °C下热解Cu-bipy-BTC的产物）显示出具有0.5至1.3nm范围内的微孔和27至46 nm范围内的中孔的多孔结构。与Cu-bipy-BTC相比，它还具有更高的ORR电催化活性，电流密度为−3.06 mA cm− 2。此外，MOF-800阴极的电荷转移电阻（1.38 Ω）远小于Cu-bipy-BTC阴极的电荷转移电阻（176.8 Ω）。MOF-800-MFC的最大功率密度为326 ± 11 mW m− 2，是Cu-bipy-BTC-MFC的2.6倍，与Pt/C-MFC（402 ± 17 mW m−2）相当。结果表明，M0 F-800的孔结构和丰富的活性位（C-N、Cu-Nχ）是提高MFC产电性能的主要原因。本研究为ORR活性催化剂修饰阴极提高MFC性能提供了技术和理论依据。
To improve the power generation of microbial fuel cell (MFC), the cathode is modified to increase its oxygen reduction reaction (ORR) activity by using a Cu, N-incorporated carbon-based material as catalyst, which obtained from pyrolyzing ORR active Cu (II)-based metal organic framework (MOF; Cu-bipy-BTC, bipy = 2,2′-bipyridine, BTC = 1,3,5-tricarboxylate). MOF-800 (the product of pyrolyzing Cu-bipy-BTC at 800 °C) shows porous structure with micropores ranging from 0.5 to 1.3 nm and mesopores ranging from 27 to 46 nm. It also exhibits improved ORR electrocatalytic activity with a higher current density of −3.06 mA cm−2compared to Cu-bipy-BTC. Moreover, the charge transfer resistance of MOF-800 cathode (1.38 Ω) is much smaller than that of Cu-bipy-BTC cathode (176.8 Ω). A maximum power density of 326 ± 11 mW m−2is achieved by MOF-800-MFC, which is 2.6 times of that of Cu-bipy-BTC-MFC and comparable with Pt/C-MFC (402 ± 17 mW m−2). The results imply the enhancements of ORR catalytic activity and electrical conductivity of MOF-800 are due to the enhanced porous structure and abundant active sites (C–N, Cu–Nχ), which result in the improved power generation of MFC. This study provides technical and theoretical validation for the MFC performance improvement by ORR active MOF-derived catalysts modified cathodes.
