Effects of hydrothermal etching and conversion on photocatalytic hydrogen evolution and overall water splitting with nanoparticulate and mesoporous TiO 2 and SrTiO 3 /TiO 2 composites

Hydrothermal treatment of mesoporous photocatalysts in diluted NaOH solution or H 2 O might be a simple and promising strategy to improve photocatalytic activities in general, as we show for TiO 2 and SrTiO 3 /TiO 2 composites.
