▎ 摘　　要

NOVELTY - Preparation of graphene involves crushing graphite oxide into small sections by mechanical shearing or milling method, heating at 250-500 degrees C and rate of 5-35 degrees C/minute for 5-120 minutes by introducing mixture of hydrogen and nitrogen or mixture of hydrogen and argon at flow rate of 10-100 mL/minute, and cooling to room temperature. USE - Preparation of graphene (claimed). ADVANTAGE - The method enables economical preparation of graphene by safe and simple process.
