▎ 摘　　要

NOVELTY - Growing nanostructured single layer graphene film involves selecting a copper foil and then annealing the selected material with graphene under mixed atmosphere of argon and hydrogen at high temperature. The annealed material is purged with methane and hydrogen and then the obtained material is cooled to room temperature under an argon atmosphere. The cooled material is subjected to ozone treatment and then the ozone-treated graphene foil substrate is immersed in an aqueous solution of silver nitrate to obtain the desired product. USE - Method for growing nanostructured single layer graphene film (claimed). ADVANTAGE - The method enables to grow nanostructured single layer graphene film in a cost-effective, environment-friendly and simple manner.
