Co-naphthalocyanine (CoNPc) was prepared by heat treatment for cathode catalysts to be used in microbial fuel cells (MFCs). Four different catalysts (Carbon black, NPc/C, CoNPc/C, Pt/C) were compared and characterized using XPS, EDAX and TEM. The electrochemical characteristics of oxygen reduction reaction (ORR) were compared by cyclic voltammetry (CV) and linear sweep voltammetry (LSV). The Co-macrocyclic complex improves the catalyst dispersion and oxygen reduction reaction of CoNPc/C. The maximum power of CoNPc/C was 64.7 mW/m(2) at 0.25 mA as compared with 81.3 mW/m(2) of Pt/C, 29.7 mW/m(2) of NPc/C and 9.3 mW/m(2) of carbon black when the cathodes were implemented in H-type MFCs. The steady state cell, cathode and anode potential of MFC with using CoNPc/C were comparable to those of Pt/C.
共酞菁钴（CoNPc）经热处理后被用作微生物燃料电池（MFC）的阴极催化剂。使用 XPS、EDAX 和 TEM 对四种不同的催化剂（炭黑、Npc/C、CoNPc/C、Pt/C）进行了比较和表征。通过循环伏安法（CV）和线性扫描伏安法（LSV）比较了氧还原反应（ORR）的电化学特性。Co 大环配合物提高了 CoNPc/C 的催化剂分散性和氧还原反应活性。在 H 型 MFC 中，当阴极采用 CoNPc/C 时，其最大功率为 0.25 mA 时的 64.7 mW/m²，而 Pt/C 的最大功率为 81.3 mW/m²，Npc/C 的最大功率为 29.7 mW/m²，炭黑的最大功率为 9.3 mW/m²。使用 CoNPc/C 的 MFC 的稳态电池、阴极和阳极电势与 Pt/C 的相当。
