Abstract | The relationship between growth kinetic and photocatalysis of SrTiO3 nanoparticles is investigated by close correlation of their growth behaviors under the different stages. The detailed structural characterizations show that SrTiO3 crystal growth does not follow the classic route. A new growth mechanism, including the first formation of SrTiO3 mesoporous sphere followed by the single crystal growth via oriented attachment, size shrinking, and Ostwald ripening, is proposed. The photocatalytic ability of the as-grown SrTiO3 products at different growth stages, checked by the degradation of methyl orange, shows different properties. The results indicate that the size, morphology, and defects of the resultant SrTiO3 products, tailored during the different growth stages, were highly responsible for the photocatalytic activity. Especially, the semicrystalline SrTiO3 mesoporous spheres produced by oriented attachment at the initial stage show the highest photocatalytic ability. |
