摘要
为提高电极利用率,制备了一种掺Pt涂层生物质活性炭纤维笼型阴极材料,并构建了以该材料为空气阴极的微生物燃料电池(Microbial Fuel Cell, MFC)。试验结果表明:涂层之后的MFC最大输出电压为329 mV,约是涂层之前电压输出的1.65倍,产电量约是涂层之前的1.53倍,由此表明掺Pt涂层阴极材料能明显提高MFC产电性能。最终确定的涂层电极最佳工艺条件为:碳粉0.5 g、聚四氟乙烯乳液(PTFE)6 mL、0.3 g Pt/C催化剂。
To improve the utilization of electrode,a novel cage-shaped activated carbon fiber electrode doped with Pt derived from biomass was prepared,and the microbial fuel cell(MFC)was constructed with this material as air cathode.The experimental results show that the maximum voltage output of the MFC is 329 mV after doping with Pt,which is about 1.65 times before the doping,and the electricity production is about 1.53 times as much as before the doping,which indicates that this novel cathode could obviously improve the electrical performance of MFC.Meanwhile,the optimum process conditions are as follows:carbon powder is 0.5 g,PTFE is 6 mL,and 0.3 g Pt/C catalyst.
