NOVELTY - Synthesizing graphene oxide-based composite material involves dissolving graphene oxide in deionized water ultrasonically to obtain dispersion, which is then mixed with iron(III) chloride hexahydrate. Sodium sulfate is added to the obtained dispersion mixture in a reaction vessel, which is placed into a water bath under insulated condition at 60-85 degrees C. The obtained dispersion mixture is cooled at room temperature, and then centrifuged to collect solidified product. USE - Method for synthesizing graphene oxide-based composite material (claimed). ADVANTAGE - The method enables to synthesize graphene oxide-based composite material that has large specific surface area in a simple, convenient and cost-effective manner. The synthesize graphene oxide-based composite material is easily separable under laboratory conditions, and also avoid the agglomeration of oxidation debris in graphene oxide in a composite material. DETAILED DESCRIPTION - Synthesizing graphene oxide-based composite material involves dissolving graphene oxide in deionized water ultrasonically to obtain dispersion, which is then mixed with iron(III) chloride hexahydrate. Sodium sulfate is added to the obtained dispersion mixture in a reaction vessel, which is placed into a water bath under insulated condition at 60-85 degrees C. The obtained dispersion mixture is cooled at room temperature, and then centrifuged to collect solidified product. The collected solidified product is treated with dilute hydrochloric acid solution to wash away present impurities from the solidified product. The obtained product is dried in vacuum to obtain desired graphene oxide-based composite material.
