Fabrication of Porous $ TiO_{2} $ Hollow Spheres and Their Application in Gas Sensing

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 prov...

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°C due to its high surface area.

abstract	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°C due to its high surface area.
