▎ 摘 要
NOVELTY - Graphene is prepared by contacting greater than or equal to 1 metal and composition containing graphene oxide under conditions sufficient to reduce greater than or equal to 1 portion of graphene oxide to graphene. USE - Preparation of graphene (claimed). ADVANTAGE - The method is suitable for batch production, safe, environmentally friendly, and non-toxic. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) system for preparing graphene comprising enclosure configured to receive greater than or equal to 1 metal and composition containing graphene oxide and mixer configured to mix greater than or equal to 1 metal and composition; and (2) kit for preparing graphene comprising greater than or equal to 1 metal, composition containing graphene oxide, and instructions for contacting greater than or equal to 1 metal and composition to prepare graphene.
