▎ 摘　　要

NOVELTY - Synthesis of a carbon network involves dissolving carbon nanodots (CNDs) in a solvent to form a CND slurry, casting the slurry onto a substrate, drying the CND slurry on the substrate to form a CND film, and irradiating the CND film with a light beam to convert at least a portion of the CND film into turbostratic graphene. USE - Synthesis of carbon network e.g. three-dimensional (3D) turbostratic graphene for energy storage device e.g. supercapacitor. Uses include but are not limited to electrochemical capacitors, batteries, hybrid supercapacitors, and pseudocapacitors. ADVANTAGE - The porous carbon network has high surface area three-dimensional graphene networks with excellent electrochemical properties, tunable and optimal morphological and electronic properties such as surface area, crystalline domains, and charge trapping centers, thus enabling use of carbon nanodots (CNDs) as electroactive components in energy storage devices such as electrochemical capacitors, supercapacitors, batteries, hybrid super-capacitor, and pseudocapacitors. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of laser-assisted conversion of carbon nanodots into three-dimensional turbostratic graphene.
