摘　　要：采用超声分散法和溶胶浸渍法制备了Mn3O4修饰电极,在微生物燃料电池(MFC)中,研究了不同方法修饰的Mn3O4阳极对MFC产电能力的影响。实验结果表明:超声分散法制备的Mn3O4作为阳极,MFC最大功率密度为0.172 W/m2,相比对照组降低了22%;产电菌在电极表面的电子传递受到了抑制。溶胶浸渍法制备的Mn3O4作为阳极,MFC最大功率密度则为0.431W/m2,相比对照组增加了93%;MFC的电荷转移内阻降低了67%,并具有赝电容特性。Mn3O4-coated electrodes were prepared by ultrasonic dispersion method and sol dipping method.They were used as the anodes of the microbial fuel cells（MFC）to study the effects of the modified methods of Mn3O4-coated anodes on electricity production.The results showed that the maximum power density of the MFC with ultrasonic dispersed Mn3O4-coated anode was 0.172 W/m2,22% lower than the bare anode.The electron transfer of the exoelectrogen was inhibited on the electrode.The maximum power density of the MFC with sol dipped Mn3O4-coated anode was 0.431 W/m2,93% higher than that of the bare anode.The charge transfer resistance was decreased by 67%.The sol dipped Mn3O4-coated anode exhibited pseudocapacitive property.
