▎ 摘　　要

NOVELTY - A graphene is prepared by dispersing graphite oxide in water under ultrasonic oscillation to obtain colloid; and under acidic or alkaline condition, taking zinc as reducing agent to reduce the oxidized graphite to obtain graphene. A weight ratio of graphite oxide and zinc oxide is 1:5.5-6.5. USE - Method for preparation of graphene (claimed). ADVANTAGE - The method uses zinc as reducing agent, which has good reducing performance, is inexpensive, and is non toxic, thus protecting health of operator and providing high environmental protection performance.
