▎ 摘　　要

NOVELTY - Preparing graphene nano bubble material involves heating the graphite raw material with oxidizing acid. The product obtained from the reaction is reacted with the intercalating agent by heating. The obtained product is heated to react with the expansion agent, and solid-liquid separation, after the reaction is performed to obtain graphite nanobubble material. The graphite nanobubble material is mechanically treated to obtain the graphene nanobubble material. USE - Method for preparing graphene nano bubble material used in preparation of adsorbents, catalysts, optical materials or energy storage materials (claimed). ADVANTAGE - The method enables to prepare graphene nano bubble material which is scientific in technology, simple and easy to implement, does not require expensive equipment and noble metals as reaction conditions, and has a high yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an adsorbent, catalyst, optical material or energy storage material, which comprises the graphene nanobubble material.
