摘　　要：以循环伏安法(CV)考察酞菁铁/碳纳米管氧还原(ORR)催化行为,并构建以磷酸缓冲溶液(PBS)和葡萄糖为阳极原料,酞菁铁/碳纳米管复合物为阴极氧气还原催化剂的双室型微生物燃料电池(MFCs)。结果表明:(1)在中性介质中,对氧还原的电催化性能要比商品化的铂碳催化剂还原电位正移了44 mV。(2)以大肠杆菌(E coli)为产电微生物,该MFC的最大输出功率密度为932.5 mW/m2,对应电流密度为2792.6 mA/m2,高于铂碳催化剂阴极的MFC。The cathodic catalyst of oxygen reduction reaction（ORR） at an iron tetrasulfophthalocyanine functionalized carbon nanotubes（FeTSPc/MWCNTs）nanocomposite was investigated by cyclic voltammetry（CV） and the two-chambers microbial fuel cell（MFC） with glucose and phosphate buffered saline（PBS） as anodic substrate,FeTSPc/MWCNTs as cathodic ORR catalyst was set up.The results show that：（1）In neutral solution,the peak potential of the ORR of FeTSPc/MWCNTs positively shifts about 44 mV in comparison with that of commercial Pt/C catalyst.（2）Escherichia coli（E.coli） was applied as the electricigenic microorganism,the maximum power density of MFC was obtained to 932.5 mW/m2,with the corresponding current density of 2792.6 mA/m2,which were higher than those of Pt/C-MFC.
