摘要： 以循环伏安法（CV）和线性扫描伏安法（LSV）考察Mo2C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%.

Abstract: The electrochemical behavior of the Mo2C  catalyzing ORR was studied via cyclic voltammetry and linear scanning voltammetry. Experimental results show that Mo2C  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 anodic 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.

Key words: Mo2C ; microbial fuel cell(MFC); cathodic catalyst; oxygen reducing reaction
