Hydrothermal synthesis of agglomerating TiO2 nanoflowers and its gas sensing

Abstract

Nanomaterials with three dimensional architectures frequently exhibit novel functional properties. In current work, a novel rutile TiO2 3D nanoflowers with the powder partly agglomerating have been successfully synthesized via a facile hydrothermal route in the saturated sodium chloride solution. In addition, the effect of the solvent in hydrothermal process was preliminarily discussed on the basis of comparative experiments. Such an unexpected morphology provides a non-trivial behavior driven by the properties of partly agglomerating TiO2 nanoflowers in gas sensing.
