Summary:The present disclosure relates to a graphene and Fe3O4-Au composite and a preparation method and a use thereof. The preparation method includes the following: firstly, preparing a thiol alkyl azide-modified Fe3O4-Au complex, and preparing an alkynylated graphene oxide by reacting a graphene oxide, which is activated by thionyl chloride, with a propargyl alcohol, and then performing a click reaction of the alkynyl group with the azide group between the thiol alkyl azide-modified Fe3O4-Au complex and the alkynylated graphene oxide with adding a catalysis under a nitrogen atmosphere condition to obtain the graphene and Fe3O4-Au composite. The method of preparing the graphene and Fe3O4-Au composite of the present disclosure has mild reaction conditions, and is simple and reliable.
