Abstract

In this study, we can successfully synthesize nano-perovskites, including nano-CaTiO3, nano-SrTiO3, and nano-BaTiO3, by a co-precipitation method. The band gap of the nano-perovskites are 3.65 eV, 3.44 eV, and 3.35 eV, for nano-CaTiO3, nano-SrTiO3, and nano-BaTiO3, respectively. The ability of photocatalysis for nano-BaTiO3 is a little bit better than other nano-perovskites. It is also observed the photocatalytic activity increases with the increasing amount of photocatalysts. Moreover, the ability of photocatalysis using a higher energy UV-light is not promoted with the low energy UV-light.
