NOVELTY - Carbon nitride material comprises nitrogen enriched carbon material. The carbon nitride material is atomically doped with one or more metal elements selected from platinum, palladium, copper, zinc. The carbon nitride material is porous and has average pore size/diameter ranging from 1-100 nanometer and has Brunauer-Emmett-Teller surface area ranging from 140-200 m^2/g. USE - Carbon nitride material. ADVANTAGE - The carbon nitride material improves electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing electrode, which involves mixing carbon nitride material with carbon black and poly(vinylidene fluoride) in ethanol under ultrasonication at room temperature to form slurry, weight ratio of the carbon nitride material, carbon black and poly(vinylidene fluoride) is 80/10/10, dropping slurry onto graphite paper to form film and drying the film at 80?oC for 24 hours, electrode comprises carbon nitride material.
