摘　　要： 以循环伏安法(CV)和线性扫描伏安法(LSV)考察Mo2C对氧还原反应(ORR)的催化行为,并采用Mo2C作为阴阳极催化剂构建MFC.结果表明,Mo2C对氧还原反应有显著的催化作用,而且其催化效果随负载量增加而增强;当以肺炎克雷伯氏菌(L17)为产电微生物、质量浓度为2 g/L的葡萄糖为燃料,阴阳极催化剂Mo2C的载量均为6.0 mg/cm2时,该MFC的最大输出功率可达1.95 W/m3,为之前报道所对应的Pt阴极材料的Mo2C基MFC最大输出功率的81.5%,Pt为阴阳极催化剂的MFC的56.3%. The electrochemical behavior of the MozC catalyzing ORR was studied via cyclic voltammetry and linear scanning voltammetry. Experimental results show that Mo2 C has significant catalysis on ORR and the catalytic effect is enhanced with the increase of the load. When 2 g/L glucose solution was as a- nodic fuel, the MFC with 6 mg/cm2 Mo2C delivering power density of 1.95 W/m3 produced 81.5% as much power density as the MFC using Pt-catalyst cathode, and 56.3% as much power density as the MFC using Pt-catalyst cathode and anode under the same conditions.
