Abstract

The present invention relates to a method for tuning shape, exposed crystal face and size of titanium dioxide by using inorganic salts and changing pH value of the reaction environment. The present invention changes the shape of titanium dioxide crystal and the exposed face thereof by adding different inorganic salts during the reaction to utilize different alkali metal ions of the inorganic salts and also can change the size of titanium dioxide crystal by tuning different pH value in the reaction. By this synthesis method, the shape and size of titanium dioxide can be tuned for different applications, such as photocatalysis, dye-sensitized solar cells, photolysis of water and other optoelectronic components or materials, to achieve their optimal efficiencies.
