Co/β-Mo2C-decorated Carbon Paper Anode for High-performance Microbial Fuel Cells

  • 摘要: 采用热处理辅助的化学法制备了Co/β-Mo2C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-Mo2C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/cm2 Co/β-Mo2C的阳极MFC最大输出功率密度和库伦效率分别为483.3 mW/cm2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.
