▎ 摘　　要

NOVELTY - Manufacture of three-dimensional graphene nanostructure involves forming graphene nano-cup spacer by mixing graphene, titanium catalyst precursor and ionic liquid, irradiating the microwave to the mixture, drying the mixture, and etching powder particles with acidic solution. USE - Manufacture of three-dimensional graphene nanostructure (claimed) used for electrode of capacitor. ADVANTAGE - The method enables efficient manufacture of three-dimensional graphene nanostructure with excellent electrochemical characteristics and high electrical capacity.
