Methods for forming porous oxide coating layer on titanium dioxide (TiO2) particle surface and titanium dioxide (TiO2) powder and film manufactured therefrom

A method of coating the nano-layer of porous oxides with hyperfine nano-sized pores on titanium dioxide (TiO2), comprising the steps of:

• providing a solution containing metallic salts;
• providing the solution of the metallic salts with a titanium dioxide (TiO2) powder;
• hydrating the metallic salts and coating the hydrates on a surface of the titanium dioxide (TiO2) powder;
• and
• forming oxides from the hydrates coated on the titanium dioxide (TiO2) powder surface.
