PURPOSE: Provided is a multi-functional composite with high absorptivity for visible rays and ultraviolet lays. CONSTITUTION: The composite comprises a support coated or impregnated with oxide and has a chemical formula of £AaDdEeOx|y£support|z, wherein 'A' is at least one component selected from a group consisting of titanium (Ti), zinc (Zn), zirconium (Zr), vanadium (V), tungsten (W) and cerium (Ce), 'D' is at least one elements selected from a group consisting of Fe, tin, V, Cr, Al, Ag, Cu, Mo, Sb, Nb and Si, 'E' is at least one compound selected from a group consisting of sulfuric acid, phosphoric acid, boric acid, hydrogen fluoride, ammonium sulfate, fluorocarbon compound, and hetero-polymer, and wherein 'a', 'd', 'e' denote mole ratio, 'a'/('d'+2) is in a range of 0.001-100, 'd' is in a range of 0-1, 'e' is in a range of 0-1 and 'a' is not less than 0, and wherein the support is a porous material such as elvan, zeolite, silica, activated carbon and apatite, or a clay such as bentonite and kaolin.
