摘　　要：通过简单的溶液衍生前驱体和煅烧法成功制备了具有微纳米结构的Mo_(2)C-C复合材料,并用作微生物燃料电池(MFC)的高性能阳极电催化剂。形态和组成表征表明,制备的Mo_(2)C-C复合材料由Mo_(2)C和C组成,具有微/纳米颗粒结构。同时材料表面含有丰富官能团,有助于提高微生物在阳极表面的附着。电化学测试结果表明,Mo_(2)C-C复合材料对阳极/微生物之间的电荷转移具有出色的电催化活性。装有微纳米Mo_(2)C-C/CF阳极的MFC的最大功率密度为1.61 W·m^(-2),明显优于商用碳毡阳极。这项工作为高性能、环保MFC阳极电催化剂提供新思路。Mo_(2)C-C composites with micro-/nanostructure as high-performance anode electrocatalyst for microbial fuel cells(MFCs)were successfully prepared by a simple solution derived precursor and calcination method.Morphological and compositional characterization indicate that the prepared Mo_(2)C-C composites consisted of Mo_(2)C and C with micro/nanoparticle structure and rich functional groups on the surface,improving the attachment of microorganisms on the anode surface.Electrochemical measurements demonstrated that the as-synthesized micro/nano Mo_(2)C-C composites exhibited an outstanding electrocatalytic activity for charge transfer between anode/microorganisms.The MFC fitted with micro/nano Mo_(2)C-C/CF anode harvested a superior power density(1.61 W·m^(-2)),significantly higher than that of commercial carbon felt anode.This work provides new ideas for high performance and environmentally friendly MFC anode electrocatalysts.
