▎ 摘　　要

NOVELTY - The synthesizing method involves synthesizing graphene oxide by using modified Hummer's method. A leaf extract is prepared using three different leaves such as peepal leafs, mango leafs, and asoka leafs. The reduction of graphene oxide is performed by the prepared leaf extract to obtain graphene nanosheets. USE - Large-scale synthesizing method of high quality graphene nanosheets. ADVANTAGE - The synthesis of graphene nanosheets by mango leaf extract provides a good quality graphene in a cost effective method. The synthesizing method provides energy efficient technique for the synthesis and produces graphene nanosheets at large scale within short duration of time and with less amount of work. The synthesizing method involves simple processing steps and low cost chemicals with high yield of the graphene product. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of the graphene oxide reduction into graphene nanosheet.
