TITANIUM DIOXIDE NANO-COMPLEX IN A CORE-SHELL STRUCTURE AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF UNIFORMLY DOPING METAL NANO-PARTICLES ON TITANIUM DIOXIDE NANO-POWDER AND UNIFORMLY COATING THE TITANIUM DIOXIDE NANO-POWDER USING A TITANIUM DIOXIDE THIN FILM
TITANIUM DIOXIDE NANO-COMPLEX IN A CORE-SHELL STRUCTURE AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF UNIFORMLY DOPING METAL NANO-PARTICLES ON TITANIUM DIOXIDE NANO-POWDER AND UNIFORMLY COATING THE TITANIUM DIOXIDE NANO-POWDER USING A TITANIUM DIOXIDE THIN FILM
PURPOSE: A titanium dioxide nano-complex in a core-shell structure and a method for manufacturing the same are provided to increase the durability of antibiotic characteristic and photo-catalytic characteristic by suppressing the oxidization of metal nano-particles.;CONSTITUTION: A titanium dioxide nano-complex(10) in a core-shell structure includes a nano-core(100) and a nano-shell(200). The nano-core is composed of titanium dioxide nano-powder(110) and metal nano-particle(130) doped to the titanium nano-powder. The nano-shell is composed of a titanium dioxide thin film which is coated on the nano-core. A method for manufacturing the titanium dioxide nano-complex includes the following: The mixed solution of a metal precursor, titanium dioxide powder, and a polar solvent. An ultrasonic wave reducing method is applied to the mixed solution to obtain a solution containing a nano-core composed of titanium dioxide nano-powder doped with metal nano-particle. A titanium dioxide precursor is added to the solution containing the nano-core to be reduced. A nano-shell composed of a titanium dioxide thin film is coated on the nano-shell.;COPYRIGHT KIPO 2012
