Abstract
Methods of preparing graphene/graphene oxide particulates under mild conditions, comprising reacting pristine graphene with hydrogen peroxide and a source of iron to oxidize the outer surface of the pristine graphene particulates in solution and yield graphene/graphene oxide particulates. Methods and articles incorporating the same are also disclosed.
Claims20
A method of preparing graphene/graphene oxide particulates, said method comprising:
- creating a reaction solution comprising an aqueous solvent system at pH≤5.0, hydrogen peroxide, and pristine graphene particulates having an outer surface;
- adding a source of iron to said reaction solution;
- stirring or agitating said reaction solution for a period of time to react hydroperoxyl radicals with said graphene particulates to oxidize the outer surface of said pristine graphene particulates in solution and yield said graphene/graphene oxide particulates;
- and
- collecting said graphene/graphene oxide particulates from said solution.
