▎ 摘 要
NOVELTY - Producing porous graphene material, comprises: (i) dispersing metal oxide nanoparticles in a solvent; (ii) adding a soluble salt and a polymer of graphitization catalyst into the product obtained in the step (i), and evenly mixing; (iii) heating the product and vacuumizing to remove the solvent; (iv) hot processing the product for 0.5-400 minutes at 500-1000 degrees C under inert atmosphere, cooling and collecting the solid product and (v) processing the solid product by using diluted acid, dissolving and removing the catalyst and the metal oxide nanoparticles. USE - The method is useful for producing porous graphene material. ADVANTAGE - The method: is simple and provided with easily available raw materials; is suitable for industrial production; and prepares graphene material in batches. The porous graphene material prepared has low oxygen content and high graphitization degree, and possess a graphene sheet layer with holes having a diameter of greater than 2 nm.
