Abstract
A modified carbon material, including a carbonaceous material and a water-insoluble modifier combined with the carbonaceous material, wherein the water-insoluble modifier is CuO, the carbonaceous material is one of or a mixture of biomass carbon or carbon black, a mass of the water-insoluble modifier is being 0.1-10 wt % of the carbonaceous material. The method for preparing the modified carbon material includes: (1) soaking the carbonaceous material in a copper sulfate solution for 5 to 36 hours, and (2) adding an alkali solution into a solution obtained in step (1) to provide a pH value ≥12, and after keeping the pH value for 0.5 to 2 hours, filtering and drying to obtain a solid. (3) using the carbonaceous material as a combustion heat source to reduce the ignition temperature, increase or reduce the peak thermal power temperature.
