▎ 摘  要

NOVELTY - Preparation of green graphene nanosheets involves mixing (i) graphite, urea peroxide and hydrogen peroxide to obtain a mixture, maintaining (ii) the mixture and processing by microwave to obtain a graphene aggregate, and ultrasonically-dispersing (iii) the graphene aggregate in ethanol. USE - Preparation of green graphene nanosheets. ADVANTAGE - The method enables simple, economical and large-scale preparation of green graphene nanosheets using economical and easily-available raw materials comprising urea peroxide and hydrogen peroxide as oxidants, without environmental pollution.
