Abstract
Surface reconstructed SrTiO nanocrystals were synthesized by a thermal treatment process in presence of NaBH and SrTiO nanocrystals. The surface reconstruction of SrTiO nanocrystals is attributed to the introduction of surface oxygen vacancies or Ti sites (such as Ti and Ti ) during the hydrogenation treatment process. The light absorption and the charge transfer ability of SrTiO nanocrystals are simultaneously enhanced due to surface oxygen vacancies or Ti sites (such as Ti and Ti ), which are beneficial to photocatalytic water splitting. Meanwhile, these defects also change the redox potential of the photocatalysts. Since there existed a synergistic effect between the three, the ratio of hydrogen to oxygen production was also regulated.
