| 摘 要： | 以循环伏安法(CV)和线性扫描伏安法(LSV)考察MnO2对氧还原反应(ORR)的催化行为,并采用MnO2作为阴极氧还原催化剂构建微生物燃料电池(MFC)。结果表明,MnO2对ORR有显著的催化作用,而且其催化效果随电解质碱性增强而增强;当以肺炎克雷伯氏菌(L17)为产电微生物、3g/L葡萄糖为燃料、1mol/LKOH溶液为阴极液时,该MFC的最大输出功率可达696.3mW/m2,对应电流密度为0.25mA/cm2。

| Abstract: | A two-chamber microbial fuel cell (MFC) was designed without any redox mediator, in which manganese dioxide (MnO2) was applied as the cathodic catalyst of oxygen reduction reaction (ORR) and Klebsiella pneumoniae as the electricigenic microorganism in anode chamber. When using 3 g/L glucose solution as anodic fuel and 1 mol/L KOH solution as catholyte, the maximum output power of MFC attained to 696.3 mW/m2, with the corresponding current density of 0.25 mA/cm2. |
