| Abstract | In this work, porous TiO(2) hollow spheres with an average diameter of 100 nm and shell thickness of 20 nm were synthesized by a facile hydrothermal method with NH(4)HCO(3) as the structure-directing agent, and the formation mechanism for this porous hollow structure was proved to be the Ostwald ripening process by tracking the morphology of the products at different reaction stages. The product was characterized by SEM, TEM, XRD and BET analyses, and the results show that the as-synthesized products are anatase phase with a high surface area up to 132.5 m(2)/g. Gas-sensing investigation reveals that the product possesses sensitive response to methanal gas at 200 degrees C due to its high surface area. |
