▎ 摘　　要

NOVELTY - Forming graphene involves heating electrolyzed coal to a temperature effective to form graphite in the presence of a flowing stream of reductant gas, where the stream of reductant gas deposits graphene onto a surface. USE - For forming graphene (claimed), which is used in nanoelectronics, composite materials, sensors to electrochemical electrodes in lithium ion batteries, solar cells, or ultracapacitors. The specific electronics applications of graphene include mobile phones, radars, transistors, data storage, touch screens, and wearable electronics. ADVANTAGE - The present method is effective and significantly reduces the cost of forming high quality graphene for commercial use.
