| 摘 要： | 阴极催化剂是影响微生物燃料电池(microbial fuel cell,MFC)性能的关键要素.为了考察不同羧基化方法改性的碳纳米管(carbon nanotube,CNT)负载Pt的催化氧还原效率,分别在80℃和95℃条件下对CNT进行了羧基化,采用浸渍-沉淀法制备了Pt/CNT催化剂(Pt/CNT-80和Pt/CNT-95),并在空气阴极MFC体系中验证了其催化氧还原效果(MFC-80、MFC-95和MFC-C).结果表明,MFC-95和MFC-80的最大功率密度分别为568.8 mW.m-2和412.8 mW.m-2,内阻分别为204.7Ω和207.7Ω,开路电压分别为0.719 V和0.651 V.而对照MFC-C的最大功率密度仅为5.4 mW.m-2,内阻为826.2Ω.XPS和XRD分析结果显示,Pt/CNT-95催化氧还原效果优于Pt/CNT-80,原因可能是95℃羧基化过程在CNT表面引入了丰富的含氧基团.
