Hydrogenated Amorphous Titania with Engineered Surface Oxygen Vacancy for Efficient Formaldehyde and Dye Removals under Visible-Light Irradiation.

Hydrogenated crystalized TiO with oxygen vacant (O) doping has attracted considerable attraction, owing to its impressive photoactivity. However, amorphous TiO, as a common allotrope of titania, is ignored as a hydrogenated templet. In this work, hydrogenated amorphous TiO (HAm-TiO) with engineered surface O and high surface area (176.
