▎ 摘　　要

NOVELTY - A carbon material supported fluorine-doped niobium carbide nanocomposite material includes fluorine-doped niobium carbide supported on carbon material, where the loading amount of niobium carbide is 10-70 wt.%, and the fluorine doping amount is 0.1-5 mol% of niobium carbide. USE - Carbon material supported fluorine-doped niobium carbide nanocomposite material used in preparation of fuel cell (claimed). ADVANTAGE - The composite material is applied to direct alcohol fuel cells and has the ability to catalyze alcohol oxidation reactions, and significantly improves the electrochemical performance such as peak current of fuel cell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing carbon material supported fluorine-doped niobium carbide nanocomposite.
