Investigation on the highly active SrTiO3 photocatalyst toward overall H2O splitting by doping Na ion

Influence of particle size and shape on the rate of hydrogen produced by Al‐doped SrTiO3 photocatalysts

“…Among them, SrTiO 3 is one of the promising materials with a bandgap of approximately 3.2 eV that can split water under UV illumination and has been widely studied 5,6 . Many researchers focus on doping aliovalent metal cations into SrTiO 3 to control the defect structure and improve photocatalytic reactivity 7,8 . In recent studies, it was found that a flux treatment in SrCl 2 —together with Al doping—can significantly increase the reactivity of SrTiO 3 for water splitting 9–11 .…”

[9][10][11] Previous experiments have shown that modifying the band bending in the space charge region either by internal or external electric fields influences the photochemical reactivity.…”

Microelectrode-based transient amperometry of O2adsorption and desorption on a SrTiO3photocatalyst excited under water

“…The SrTiO 3 particles were doped with Al cations in this study to enhance water-splitting efficiency by limiting electron-hole recombination. Transient absorption studies 40,41 showed recombination rate in In addition, the hypothesized hole-induced vacancy creation is a side-reaction that is problematic for photocatalyst durability. Durability of the Al-doped SrTiO 3 photocatalyst was enhanced over a span of 1300 h under simulated sunlight irradiation by loading the CoO y cocatalyst.…”

Advances in Z‐scheme semiconductor photocatalysts for the photoelectrochemical applications: A review

“…Furthermore, it is possible to combine properties, such as ferroelectricity or piezoelectricity, with the photocatalytic effect to improve photocatalytic activity. The perovskite photocatalysts can be classified into the following categories: titanates, SrTiO 3 [112][113][114][115][116][117][118] and BaTiO 3 119-123…”
