Hydrothermal synthesis and formation mechanism of photocatalytically active SrTiO3 nanocrystals using anatase TiO2 with different facets as a precursor

The crystal facets of anatase TiO₂ precursors could not only affect the hydrothermal crystallization of SrTiO₃ but also have a significant influence on their photoelectrochemical performance as well as photocatalytic hydrogen production activities.
