Abstract
A method for removing a carbonization catalyst from a graphene sheet, the method includes contacting the carbonization catalyst with a salt solution, which is capable of oxidizing the carbonization catalyst.
Claims18
A method for removing a carbonization catalyst from a graphene sheet, the method comprising:
- contacting the carbonization catalyst with a non-acidic salt solution, which is capable of oxidizing the carbonization catalyst through loss of electrons.
A method for transferring a graphene sheet, the method comprising:
- removing a carbonization catalyst from a graphene sheet by contacting the carbonization catalyst with a neutral salt solution or a basic salt solution, which is capable of oxidizing the carbonization catalyst through loss of electrons;
- and
- transferring the graphene sheet with the carbonization catalyst removed to a position on a substrate or a device.
