Abstract
Provided is a method for preparing a graphene material from an industrial hemp material by laser induction, which uses a skin, a stem and/or a root of industrial hemp as a carbon precursor-containing material and reduce the carbon precursor-containing material into graphene by laser induction, so as to prepare graphene, graphene quantum dots, a graphene mesoporous material and a graphene composite material.
