NOVELTY - Preparation of reduced graphene involves wetting filter paper with 1% calcium chloride solution, adding graphene oxide solution, washing filter paper with deionized water, air-drying or drying in oven, removing thin layer of graphene oxide from filter paper, placing trigger material and thin layer of graphene oxide in a container, placing container in a microwave oven and irradiating under microwave conditions for certain period of time. USE - Preparation of reduced graphene (claimed). ADVANTAGE - The method enables simple, rapid, economical, energy-efficient and environmentally-friendly preparation of reduced graphene with high quality, and without the need for inert gas atmosphere protection.
