α-MoC在无介体微生物燃料电池阳极的应用研究

Study ofα-MoC on the anode of mediator-less microbial fuel cells

采用溶体法结合碳热还原法制备了碳化钼,用XRD表征了碳化钼的结构,用SEM观察了所制备碳化钼的形貌。使用循环伏安法和交流阻抗法测试了碳化钼的电催化性能。把制备的碳化钼用于无介体微生物燃料电池阳极,电池最大功率密度达到商业铂碳的92%,表现出优越的电催化性能和良好的生物相容性。因此α-MoC可望成为一种具有广泛应用前景的无介体微生物燃料电池阳极材料。

α-MoC were prepared by dissolution method combined with carbon thermal reduction method.The structure ofα-MoC had been characterized by XRD,and the morphology was observed with scanning electron microscope（SEM）.The electro catalytic activity ofα-MoC was measured by cyclic voltammetry（CV）and electrochemical impedance spectroscopy（EIS）.When theα-MoC was used in the anode of mediator-less microbial fuel cells（MFCs）,the MFCs produced 92% as much power density as the MFCs using Pt-catalyst anode,demonstrating the superior electric catalytic properties and good biocompatibility ofα-MoC.α-MoC will be expected to be a promising anodic material for meditor-less MFCs.
