▎ 摘　　要

NOVELTY - Graphene oxide has appearance of oxidized graphite alkene which is shuttle and/or strip. USE - Graphene oxide. ADVANTAGE - The graphene oxide is safe, eco-friendly, cost effective, simple and easy to operate, avoids the graphene oxide on agglomeration phenomenon and improves the convenience of oxidation graphene application. It consumes low energy and is very suitable for application in industry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene oxide, which involves: (A) electrolyzing graphite, where anode is graphite electrode and cathode is graphite electrode or platinum electrode; (B) adding electrolyte and aqueous solution of sodium hydroxide at 1-8 Volt and 0.01-0.5 Ampere for 60-1440 minutes; and (C) separating and drying graphene oxide powder.
