NOVELTY - Preparing activated carbon involves collecting fresh silkworm generated after feeding the graphene to silkworm, drying and removing impurities, crushing the dried silkworm in the tubular furnace under the protection of inert gas for heating precarbonizing and mixing the activator under inert gas while heating. The obtained silkworm is activated with hydrochloric acid solution and washed with water to neutral to obtain activated carbon. USE - Method for preparing activated carbon. ADVANTAGE - The method enables to prepare activated carbon in simple, cost-effective and eco-friendly manner, and has high specific surface area of 1300 square meter per gram, promotes graphene active carbon composite material, stable and reliable quality and good consistency.
