Synthesis and Characterization of SrTiO3 Nanoparticles Prepared from Layered Titanate Nanotube
由层状钛酸盐纳米管制备SrTiO3纳米粒子及其表征

A series of nanoparticle SrTiO3 samples were simply synthesized by hydrothermal method using layered titanate nanotube and Sr(Ac)2 as precursors. The samples were characterized by using powder X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), photoluminescence (PL), Raman spectroscope and specific surface area measurement. The measurement results show that the diameter distribution of prepared SrTiO3 nanoparticles with disordered pores is mainly in the range of 10--30nm, and with the increase of reaction temperature or reaction time, diameter of the nanoparticles increases, whereas specific surface area and photocatalytic activity for degradation of methylene blue decrease.
