摘要
构建了单腔室微生物燃料电池(MFC),分别以乙酸钠、丁二酸、蔗糖及对苯二甲酸(TA)为底物,研究了Pt-C、聚苯胺(PANI)、碳纳米管(MWNTs)和PANI-MWNTs分别作为阴极催化剂的MFC产电性能。研究结果表明:分别以乙酸钠、丁二酸、蔗糖及TA为底物时,PANI-MWNTs阴极可获得最大开路电压分别为445,457,460,410 mV,最高功率密度分别为371,374,429,317 mW/m2;PANI-MWNTs阴极具有与Pt-C阴极接近的产电性能,反应35 h时,Pt-C阴极对上述4种底物的COD去除率分别为95.8%、95.9%、96.4%和89.1%;PANIMWNTs阴极分别为96.6%、97.0%、95.6%和97.3%。
A single-cell microbial fuel cell （MFC） was constructed using sodium acetate, succinic acid, sucrose and terephthalic acid （TA） as substrates and Pt-C, polyanilene（PANI）, carbon nanotube（MWNTs） and PANI-MWNTs as cathode catalysts respectively. The electricity generation capability of the MFC was investigated. The results show that： When sodium acetate, succinic acid, sucrose and TA are used as substrates respectively, the largest open circuit voltages of Pt-C cathode are 445, 457, 460, 410 mV, and the highest power densities are 371, 374, 429, 317 mW/m2 respectively. The electricity generation capability of MFC with PANI-MWNTs cathode is close to that with Pt-C cathode. After the reactions for 35 h using the 4 substrates, the COD removal rates by Pt-C cathode are 95.8%, 95.9%, 96.4% and 89.1%, while those by PANI-MWNTs cathode are 96.6%, 97.0%, 95.6% and 97.3% respectively.
