▎ 摘　　要

NOVELTY - A boron-substituted graphene oxide electrode is prepared as follows. Graphite oxide is ultrasonically dispersed in water, filtered, and dried to obtain graphene oxide. Graphene oxide is added to a container filled with water and metal collector at the bottom, stirred, allowed to stand, and deposited for 12-48 hours. Metal-rich graphene oxide is collected and dried, and the obtained electrode is placed in a reactor, argon gas/borane mixed gas is supplied, and substitution reaction is carried out to obtain a boron-substituted graphene oxide electrode. USE - Boron-substituted graphene oxide electrode is used in electrochemical field. ADVANTAGE - The boron-substituted graphene oxide electrode can be prepared by a simple method, without agglomeration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of boron-substituted graphene oxide electrode.
