▎ 摘　　要

NOVELTY - Production of small particles involves engraving graphene to define super pores having average pore size of less than 0.5 nm, major diffraction peaks at 2( theta ) values of approximately 9.5 degrees , approximately 29 degrees , and approximately 44 degrees analyzed using X-ray diffraction, and BET specific surface area of greater than 2000 square meters per gram. The engraved graphene comprises a thin film graphene, a graphene hybrid composite, a graphene nanoplatelet, and/or a graphene flower. USE - Production of small particles used as reinforcement additive, nanofiller, catalyst, and electrocatalyst used in battery electrode and for producing charge transfer interface for multi-layer device for fuel cell, solar cell, supercapacitor, and lithium ion battery (all claimed). ADVANTAGE - The method efficiently engraves graphene to produce particles having power of adsorbing a large quantity of fluid. The adsorption improves charge exchange and charge transfer between different materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for system, which comprises a product comprising a component comprising an electrocatalyst, supercapacitor, and/or battery, and engraved graphene having surface intentionally engraved to define super pores and comprising nanocarbon.
