▎ 摘　　要

NOVELTY - To round bottom flask, absolute ethanol is added, placed in water bath at 40 degrees C and 1 g pluronic F127 (RTM: hydrophilic nonionic surfactant) is dissolved with stirring. After the solution is clear, 5 g 20 wt.% ethanol solution of phenolic resin is added, stirred for 10 minutes, and graphene oxide-activated carbon fibers (GO-ACF) are added. Plates are transferred to oven at 100 degrees C, thermally polymerized, baked under nitrogen atmosphere, maintained for 4 hours, and cooled, to obtain activated carbon fiber-loaded mesoporous carbon-graphene layered composite material. USE - Preparation of activated carbon fiber-loaded mesoporous carbon-graphene layered composite material used as electric-Fenton system oxygen diffusion cathode material used in cathode diffusion of oxygen degradation of endocrine disrupting chemical e.g. dimethyl phthalate (all claimed). ADVANTAGE - The method efficiently provides activated carbon fiber-loaded mesoporous carbon-graphene layered composite material having excellent conductivity and high surface area. DETAILED DESCRIPTION - 12.2 g Phenol is added to a round-bottomed flask, placed at 43 degrees C water bath and stirred to dissolve. An aqueous solution containing 20 wt.% 2.6 g sodium hydroxide is added to the resultant material, stirred for 10 minutes, and 21 g 37 wt.% formaldehyde solution is dripped at 50 degrees C. The reaction mixture is stirred at 79 degrees C for 1 hour, and the reaction product is cooled to room temperature and 0.6 mol/L hydrochloric acid is added. The reaction product is adjusted to the pH of 6.9, and water is removed at 50 degrees C by rotary evaporation, to obtain phenolic resin carbon source as yellow oily product which is then diluted using 20 wt.% absolute ethanol. 20 mL 98 wt.% Sulfuric acid, 5 g phosphorus pentoxide and 5 g potassium persulfate are added to a round bottom flask, mixed, heated at 80 degrees C and 10 g graphite powder is added. The resultant mixture is reacted for 6 hours, cooled to room temperature and 50 mL distilled water is added and filtered. After washing, the solid is dried in vacuum at 60 degrees C to obtain graphite oxide. 2 g Graphite oxide and 50 mL 98 wt.% sulfuric acid are added to 250 mL three-necked flask, mixed in ice-water bath to 0 degrees C, and 17 mL 65 wt.% nitric acid is added. The reaction mixture is left still at 4 degrees C, and 7.5 g potassium manganate and 100 mL distilled water are added and stirred at 35 degrees C for 4 hours. The resultant mixture is heated at 60 degrees C, stirred for 15 minutes, and 80 mL distilled water is added. The reaction temperature is then maintained at 60 degrees C, and 20 mL 30 wt.% hydrogen peroxide is added and stirred until no bubbles. The mixture is then cooled to room temperature, suction-filtered, and washed using 4 L 3.7 wt.% concentrated hydrochloric acid. The obtained cake is then dispersed in distilled water, washed, and obtained solid is dried in vacuum at 60 degrees C for 12 hours, to obtain graphene oxide. The resultant product is then powdered using mortar to obtain graphene oxide powder. To 20 g water, graphene oxide is uniformly dispersed in a petri dish, and 3x 3 cm carbon fibers are added and dried at 60 degrees C for 24 hours to obtain graphene oxide-activated carbon fibers (GO-ACF). To 20 g weighed round bottom flask, absolute ethanol is added, placed in water bath at 40 degrees C and 1 g Pluronic F127 (RTM: hydrophilic nonionic surfactant) is dissolved with stirring. After the solution is clear, 5 g 20 wt.% ethanol solution of phenol resin is added, stirred for 10 minutes, and GO-ACF is added. Plates are transferred to an oven at 100 degrees C, thermally polymerized for 24 hours, baked at 800 degrees C under nitrogen atmosphere, maintained for 4 hours, and cooled to room temperature, to obtain activated carbon fiber-loaded mesoporous carbon-graphene layered composite material.
