▎ 摘　　要

NOVELTY - Radial graphene cluster preparation involves providing an aqueous dispersion of graphene, uniformly mixing oily organic solvent and the reducing agent to form a mixed solution, adding aqueous graphene dispersion to the obtained mixed solution, and then performing instantaneous heating to obtain the radial graphene cluster having high light absorption properties. USE - Method for preparing radial graphene cluster with high light absorption property. ADVANTAGE - The method prepares the radial graphene cluster in a simple, cost-effective and eco-friendly manner with controlled size and great significance in photoelectrocatalysis. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic image of the prepared radial graphene cluster.
