METHOD FOR MANUFACTURING TUNGSTEN OXIDE NANO STRUCTURES USING LIGHT-INDUCED ANODIZATION

摘要

PURPOSE: A manufacturing method for a tungsten oxide-nano porous structure using a light source is provided to implement anodization on a tungsten thin film by the irradiation of the light source, thereby more thickly forming the tungsten oxide-nano porous structure compared with a case of no irradiation of the light source. CONSTITUTION: A manufacturing method for a tungsten oxide-nano porous structure using a light source includes: a step of implementing anodization on a tungsten thin film by the irradiation of the light source inside an electrolyte; and a step of forming the tungsten oxide-nano porous structure at the tungsten thin film by the anodization. The electrolyte for the anodization is a glycerol solution including K2HPO4. The anodization is implemented at voltage of 30 to 8oV for 1 to 24 hours. The tungsten oxide-nano porous structure is formed to be longer compared with a case of no irradiation of the light source, and is a cylindrical nano porous structure straightened in a direction. A hydrolysis electrode is formed with the thin film of the tungsten oxide-nano porous structure manufactured by one of the methods.
