Outline of Final Research Achievements

This project aimed at preparation of doped SrTiO3 photocatalysts that were more active than the commonly-used Rh-doped SrTiO3 by designing functional multilayer structures consisting of highly-crystalline core and light absorber shell. SrTiO3:La,Rh that showed the photocatalytic hydrogen evolution activity equal to or higher than SrTiO3:Rh was produced by applying well-crystalline SrTiO3 as the core and SrTiO3 enriched with LaRhO3 content as the shell. It was demonstrated that immobilizing a hydrogen evolution photocatalyst and an oxygen evolution photocatalyst on the same conductive layer upgraded the activity of the photocatalytic system in the water splitting reaction via the two-step photoexcitation.
