NOVELTY - Preparing graphite alkenyl carbonate cobalt catalyst involves using graphene (RGO) as catalyst support and cobalt acetate as cobalt source, adding concentrated sulfuric acid, subjecting to hydrothermal method, and calcining at high temperature to obtain efficient catalytic cyclohexene at room temperature into cyclonene graphite alkenyl carbonate. The graphite powder and sodium nitrate is added in 500 mL three-mouth flask for processing for 20-30 minutes, and transferred mixture to constant-temperature in water bath. USE - Method for preparing graphite alkenyl carbonate cobalt catalyst for cyclohexene oxidation (claimed). ADVANTAGE - The method enables to prepare graphite alkenyl carbonate cobalt catalyst that has excellent catalytic performance, and in simple, eco-friendly and cost effective manner. DETAILED DESCRIPTION - Preparing graphite alkenyl carbonate cobalt catalyst involves using graphene (RGO) as catalyst support and cobalt acetate as cobalt source, adding concentrated sulfuric acid, subjecting to hydrothermal method, and calcining at high temperature to obtain efficient catalytic cyclohexene at room temperature into cyclonene graphite alkenyl carbonate. The graphite powder and sodium nitrate is added in 500 mL three-mouth flask for processing for 20-30 minutes, and transferred mixture to constant-temperature in water bath. The temperature is controlled at 0-10 degrees C, stirred and reacted for 1-2 hours. The potassium permanganate is added in three-mouth flask, stirred for 405 hours, and reacted at 30-40 degrees C. The temperature is raised to 90-100 degrees C for 30-40 minutes. The diluted sulfuric acid is added, stirred and reacted for 30-40 minutes to obtain graphite oxide (GO). The 30-40 mL hydrogen peroxide is added to remove residual oxidant in the mixture. The mixture is filtered, and washed by using 30-40 mL diluted hydrochloric acid for 1-2 times and 30-40 mL of hydrogen peroxide for 1 times. The solution is filtered, and solid is dispersed in hydrogen peroxide for 1-2 hours to obtain uniform and stable dispersion liquid. The graphite oxide is dispersed in cobalt acetate tetrahydrate, urea and sodium borate in beaker, and stirred. The mixture is transferred into reaction kettle with polytetrafluoroethylene lining at 120-140 degrees C for 10-12 hours. The mixture is cooled, washed with absolute ethyl alcohol for 2-3 times, and placed in muffle furnace at 200-250 degrees C for 2-3 hours, and crushed to obtain graphite alkenyl carbonate cobalt catalyst.
