▎ 摘　　要

NOVELTY - A porous nanostructure comprises a graphene layer comprising several laminated graphene and having pores formed on a surface or inside, and metal particles embedded in a graphene filler. USE - Porous nanostructure. Uses include but are not limited to vibration absorber, sound absorber, shock absorber, catalyst support, separation membrane, hydrogen storage material, composite material, sensor, catalyst, ultra-high-capacity storage battery, etc. ADVANTAGE - The porous nanostructure has excellent mechanical strength, hydrogen storage capability, electrical and chemical properties, and energy storage capability, and high specific surface area. The porous nanostructure can be manufactured by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of porous nanostructure, which involves dispersing a metal compound in graphene and irradiating microwave to graphene at least once.
