Abstract

We investigate the role of hydrogenation on titanium dioxide (TiO ₂) by using DFT U calculations. We find that hydrogenation on oxygen is more favorable than on titanium, which reduces Ti⁴ into Ti ³ on the surface and introduces mid-gap state into TiO₂ for enhanced optical absorption. © 2013 AIP Publishing LLC.
