Performance Improvement of Microbial Fuel Cell for Electricity Generation by Composite Graphene-Carbon Nano-Tube Modified Anode

  • 摘要: 〖JP〗石墨烯疏水性及层间-共轭极大地影响了其生物相容性和分散性,难以有效修饰电极. 文章通过将石墨烯与碳纳米管混合,利用二者之间的非共价结合,消除了石墨烯单一修饰电极的缺点,并通过浸渍法制备了石墨烯-碳纳米管复合碳纳米材料电极. 扫描电镜观察表明,石墨烯与碳纳米管被牢固地固定在碳毡电极表面,形成了复合均一层. 将复合电极用作微生物燃料电池(MFC)的阳极,〖JP+1〗显著改善了MFC的产电性能. 复合阳极的MFC的最大功率密度(760.7 mW/m2)比空白碳毡阳极MFC的(228.8 mW/m2)高2.36倍,因为复合电极显著降低了阳极的电子传递阻力,减轻了阳极极化,改善了阳极电化学性能. 复合碳纳米材料修饰阳极的电子传递阻抗(39.8 )比空白碳毡阳极的(248.7)低84%.〖JP〗
    Abstract: The biocompatibility and dispersity of graphene are deteriorated due to its hydrophobicity and - conjugated effect which make it difficult to modify carbon-based electrodes. This problem was solved by mixing graphene with carbon nano-tube through non covalent binding in this study and the composite graphene-carbon nano-tube modified electrode was prepared by the dip method. Observation by the scanning electron microscope clearly indicated that the surface of the carbon felt electrode was covered by the homogeneous layer of graphene-carbon nano-tube. The electricity generation performance of the microbial fuel cell (MFC) was greatly improved by the composite graphene -carbon nano-tube modified anode. The MFC with the modified anode produced a maximum power density of 7607 mW/m2 which was 236-fold higher than that produced by the MFC with a bare carbon felt anode (2288 mW/m2). The electron transfer impedance of the anode was significantly decreased by the composite graphene-carbon nano-tube, with 398 for the modified anode and 2487 for the bare anode, which could explain the performance improvement of MFC.
