METHOD OF GRAPHENE-CNT COMPLEX STRUCTURE FOR WATER TREATMENT AND MEMBRANE USING THE SAME

摘要

Disclosed are a method for manufacturing a graphene-carbon nanotube complex structure for water treatment and a method for manufacturing a membrane using the same. The method for manufacturing a graphene-carbon nanotube complex structure according to an embodiment of the present invention comprises: a first step for synthesizing graphene on the surface of metal powder using a chemical vapor deposition method; a second step for forming a hollow graphene-carbon nanotube complex structure by removing the metal powder and synthesizing a carbon nanotube on the surface of the graphene; a third step for functionalizing metal oxide including Fe_3O_4 and/or Fe^0 on the surface by modifying the surface of the graphene-carbon nanotube; and a fourth step for additionally functionalizing a photocatalyst on the surface.
