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。 The molybdenum carbide was prepared by the solution method combined with the carbothermal reduction method. The structure of the molybdenum carbide was characterized by XRD. The morphology of the molybdenum carbide was observed by SEM. The electrocatalytic properties of molybdenum carbide were tested by cyclic voltammetry and AC impedance method. The prepared molybdenum carbide was used as an anode in a dielectric-free microbial fuel cell. The maximum power density of the battery reached 92% of commercial platinum carbon, showing excellent electrocatalytic performance and good biocompatibility. Therefore, α-MoC is expected to become a promising anode-free anode material for microbial fuel cells.
