Hybrid density functional study of band gap engineering of SrTiO3 photocatalyst via doping for water splitting

Y. S. Hou, S. Ardo, R. Q. Wu

Perovskite SrTiO3 (STO) is an attractive photocatalyst for solar water splitting, but suffers from a limited photoresponse in the ultraviolet spectral range due to its wide band ga…
