COMPOSITE CONTAINING METAL COMPONENT SUPPORTED ON GRAPHENE, PREPARING METHOD OF THE SAME, AND USES OF THE SAME

摘要

PURPOSE: A composite including a zerovalent metal and a metal oxide of the zerovalent metal, a manufacturing method thereof, a pollutant removing composition including the same, and a pollutant removing method using the same are provided to be well dispersed in water or in an organic solvent, to easily attach to a pollutant including a heavy metal, an inorganic pollutant, an organic pollutant and a microorganism, and to be stable in air. CONSTITUTION: A composite includes a metallic component supported by graphene(100), and the metallic component includes a zerovalent metal(140), a metal oxide of the zerovalent metal, or a mixture of the zerovalent metal and the metal oxide of the zerovalent metal. The zerovalent metal is selected among Fe, Pd, Pt, Au, Ru, Ir, Rd, Ti, Co, Ni, Cu, Zn, Cr, V, Al, Sn, In, Ce, Mo, Ag, Se, Te, Y, Eu, Nb, Sm, Nd, Ga and Gd, or their combinations. The graphene includes a reduced graphene oxide. The composite is porous. The weight ratio of the zerovalent metal and the metal oxide of the zerovalent metal is 1:1 to 1:5. The graphene includes multiple graphene layers, and the metallic component is inserted between the graphene layers or is supported by the surface of the graphene layer.
