THE PRODUCING METHOD OF PHOTOCATALYST OF NANOROD-STRUCTURAL TITANIUM DIOXIDE CONTAINING COTTON THREAD INGREDIENTS

摘要

PURPOSE: A manufacturing method of a titanium dioxide nanorod structure is provided to improve the restrictive activity for a light source of an optical catalyst by doping an alkali metal of a cotton yarn. CONSTITUTION: A manufacturing method of a titanium dioxide nanorod structure containing a cotton thread comprises the following steps: dipping the cotton thread to a precursor mixed solution by using the cotton thread as a template; hydrolyzing a titanium dioxide precursor filled in the cotton thread to form a titanium dioxide nanoparticle; and plasticizing in 500~800deg C to remove the cotton thread. The titanium dioxide precursor is doped with an alkali metal selected from either potassium or magnesium.
