| titleOfInvention | Photocatalyst of nanostructural titanium dioxide and the producing method hereof with polycarbonate membrane |
| abstract | The present invention relates to a method for producing a nanocatalyst of a titanium dioxide photocatalyst using a template synthesis method, and more particularly, to a method for synthesizing a tube type titanium dioxide nanostructure. The nanostructure using the template synthesis method has a specific surface area of about 300 times larger than that of the general coating method, and thus the efficiency of the catalyst is also increased proportionally. In the present invention, it was intended to produce a titanium dioxide photocatalyst that maximized the activity of the catalyst using the template synthesis method.n n n In the present invention, titanium tetrachloride or titanium alkoxide is used as a starting material, and hydrogen peroxide or 2,4-pentanediol, which is a hydrolysis retardant, is added to prepare a titanium nanosol sol solution, which is a fine nanosol. After adhering to the stationary phase using a binder, it is calcined between 50 and 100 ℃ using a hydrothermal reactor to harden the titanium dioxide sol in the membrane, and then it is hollowed out by calcining it between 100 and 1000 ℃ using an electric furnace. Provided is a method of manufacturing a tube type titanium dioxide nanostructure.n n n The titanium dioxide nanostructures prepared according to the present invention have a specific surface area because they are manufactured in a hollow tube type, not in a full fibrous type such as a case where a titanium dioxide sol is made by a conventional method and placed in a membrane mold. And the efficiency of the catalyst increases accordingly. |
