▎ 摘  要

NOVELTY - Preparing fluorine-doped graphene-supported copper(II) oxide composite material comprises (1) dissolving graphene oxide in water, ultrasonically dispersing to form a dispersion, placing the dispersion in an ice-water bath low temperature environment and adding trifluoroacetic acid, uniformly mixing, transferring the mixed solution to high temperature environment of 120-180degreesC for 10-30 hours, reacting, after the reaction, washing the obtained solid using distilled water, drying and grinding to obtain fluorine-doped graphene, (2) adding obtained fluorine-doped graphene into a solvent, and (3) placing the obtained intermediate product in a nitrogen atmosphere, heating to 380-420degreesC, calcining at this temperature for 1-3 hours, and obtaining fluorine-doped graphene-supported copper(II) oxide composite material. USE - The composite material is useful in catalytic thermal decomposition (claimed). ADVANTAGE - The method: enables the loaded metal nanoparticles to be loaded on graphene with controllable morphology and uniform distribution; enhances the ability of the dispersed nanoparticles to promote electron transfer in the reaction process; and improves the heat transfer performance to achieve the purpose of improving and stabilizing the burning speed of solid fuel in the combustion process and reducing the pressure index.
