C-encapsulated TiOnanoparticles for selective and ultrahigh sensitive detection of formaldehyde.

The current study concerns development of fullerene-C-encapsulated TiOnanoparticles hybrid for an efficient detection of volatile organic compounds (VOCs). The nanocomposite was synthesized via chemical route by using hydrated fullerene-Cand sol-gel derived undoped-type TiOnanoparticles. The nanocomposite was characterized morphologically and structurally comparing with pure Cclusters and pure TiOnanoparticles as the reference materials.

Oxygen vacancy modulation of titania nanotubes by cathodic polarization and chemical reduction routes for efficient detection of volatile organic compounds.

In this work, we have synthesized a highly ordered TiO nanotube array by an electrochemical anodization method. Then the oxygen vacancy level of the TiO nanotubes was tuned by two different methods: i.e.
