Doping TiO 2 with noble metals, transition metals, cations, anions have yielded very promising results in enhancing photocatalytic activity of TiO 2 in the visible region and its role in generating alternate forms of energy. Noble metals in general can effectively slow down carrier recombination. However, the study of Pd and Ni as dopant can lead t...

Doping of Anatase TiO2 is a successful method to facilitate its photocatalytic activity to shift to the visible region. While noble metals in general can effectively slow down carrier recombination, the study of Pd doping in anatase TiO2 can unravel its potential as a visible light photocatalyst. Our first principles study indicate that the electro...

The use of two-dimensional sheets exclusively composed of reactive facets of TiO2 catalyst to explore the possibility of enhanced photocatalytic activity has been an exciting research frontier recently. Using first principles calculations, in this paper we investigate the optical properties of bulk and two-dimensional TiO2 nanosheets, pointing out...

Using first-principles density functional theory, the modulated electronic and optical properties of TiO 2 with Pt/Ag substitutional dopants with varying concentration are investigated. Our calculations reveal the significant decreasing trend in the band gap of TiO 2 while increasing the Pt (direct band gap) and Ag (indirect band gap) impurity conc...
