The invention relates to a vanadium nitride-porous carbon nanocomposite material and a preparation method and application thereof. The method extracts V in an oxovanadate solution by extraction, thereby reducing the influence of the preparation process on the purity of vanadium species in the oxvanadate solution. requirements, the cost of the preparation process is reduced, the average particle size of vanadium nitride in the vanadium nitride-porous carbon nanocomposite prepared by the method of the present invention is 2-10 nm, and it is uniformly distributed on the porous carbon, and the porous carbon The composition of the compound comprises graphitic carbon and amorphous carbon, thereby having excellent electrical conductivity and large specific surface area; the V species in the vanadium nitride-porous carbon nanocomposite prepared by the method of the present invention is mainly in the form of vanadium nitride exists, and its content can reach up to 42.5%. |
