▎ 摘 要
NOVELTY - An environmentally friendly graphene material preparing method involves mixing red phosphorus with graphite, where graphite as a raw material and red phosphorus as an auxiliary material and performing high-energy ball milling on the mixed powder and adding the powder to water and heating to 50-80 degrees C after ball milling, followed by adding concentrated nitric acid to carry out the reaction. The solution containing the powder is centrifuged after the reaction is completed and washed with water to obtain the finished product. USE - Method for preparing environmentally friendly graphene material. ADVANTAGE - The method enables preparing graphene material in simple and cost effective manner and reducing the pollution caused during the preparation process.
