摘　　要：采用热处理辅助的化学法制备了Co/β-Mo_(2)C双金属碳化物,将其作为微生物燃料电池(MFCs)阳极催化剂.采用扫描电子显微镜(SEM),X-射线衍射(XRD)和X射线光电子能谱(XPS)等手段研究了形貌和组成,采用电化学交流阻抗(EIS)法、循环伏安(CV)法和单室空气阴极微生物燃料电池(MFC)研究了其电化学性能.结果表明:Co/β-Mo_(2)C具有良好的电催化性能以及出色的微生物相容性.含有3 mg/cm^(2) Co/β-Mo_(2)C的阳极MFC最大输出功率密度和库伦效率分别为483.3 mW/cm^(2)和3.7%,分别是未修饰的碳纸阳极MFC的1.30倍和1.68倍.该研究可为开发高性能的微生物燃料电池阳极催化材料提供新思路.Bimetallic carbide Co/β-Mo_(2)C was prepared with the thermal treatment-assisted chemical method and used as an anode catalyst for Microbial Fuel Cells(MFCs).The morphology and content of Co/β-Mo_(2)C was studied with the scanning electron microscope(SEM),X-ray diffraction(XRD),and X-ray photoelectron spectroscopy(XPS).Furthermore,the cyclic voltammetry(CV),the electrochemical impedance spectroscopy(EIS)and a single-chamber air-cathode Microbial Fuel Cell(MFC)were used to study the electrochemical performance of Co/β-Mo_(2)C.The results showed that due to the prominent electrochemical activity and excellent biocompatibility,the MFC device equipped with 3 mg/cm^(2) Co/β-Mo_(2)C-decorated carbon paper anode delivered a power density of 483.3 mW/cm^(2),and a coulomb efficiency of 3.7%,which are 1.30 and 1.68 times those of the pristine carbon paper anode MFCs respectively.This work provides a new path for the explorer of high-performance anodic catalysts for MFCs application.
