A SrTiO3 photoanode prepared by the particle transfer method for oxygen evolution from water with high quantum efficiencies.

A photoanode prepared from flux-synthesized Al-doped SrTiO3 by the particle transfer method with a Ta contact layer exhibited a high IPCE of 69% at 320 nm. The photocatalytic activity of SrTiO3 particles was very sensitive to the synthesis method used to make the SrTiO3 particles, while its photoelectrochemical performance was not.
