In-gap states enhance the hydroxylation of c(6 × 2) terminated SrTiO3.
Strontium titanate (SrTiO3) has been established as a model perovskite for studying fundamental surface-molecule interactions and mechanisms in photo-electrocatalysis. Here, we investigated the electronic structure and water adsorption behaviour of Nb-doped, SrO-enriched SrTiO3 surfaces prepared by HCl-HNO3 etching fol...
