| Abstract: | Porous SrTiO3 spheres were successfully synthesized by a convenient hydrothermal method, employing SrCl2 as Sr source and titanate nanotube as Ti precursor. In this reaction, when short titanate nanotube was used as Ti precursor, porous SrTiO3 spheres were generated for the aggregation of the nanotube@SrTiO3 heteronanostructure. Whereas long titanate nanowire was used as the Ti precursor, solid SrTiO3 spheres were obtained due to the SrTiO3 which grows up gradually on the titanate nanowire. The morphology and the pore size of the SrTiO3 sphere structures can be easily controlled by simply adjusting the reaction time, reaction temperature and the Ti precursor. The porous SrTiO3 spheres exhibited enhanced photocatalytic activity which could achieve 100% degradation of Rhodamine B with a UV irradiation for 20 min. |
