Photoelectrochemistry [1-7] and photocatalysis [8-39] using semiconductor materials for the photon energy conversion have extensively been studied since the Honda-Fujishima effect [40] was reported.
Therefore, making new valence bands or electron donor levels above the valence band consisting of O2p orbitals (band engineering) is required for the sensitization of the TiO2 and SrTiO3 photocatalysts to visible light.
For example, visible-light responses of nickel and either tantalum or niobium-codoped TiO2 and SrTiO3 are due to the electronic transition from the electron donor levels consisting of occupied Ni2+ 3d orbitals to the conduction bands of host materials.
These are typical profiles for doped materials.
In the Z-scheme photocatalyst system, the SrTiO3:Cr/Ta and SrTiO3:Rh photocatalysts developed by transition metal cation doping are key materials.
