为了研究铁电性对光催化过程的影响，我们合成了单分散的铁电BaTiO_3纳米粒子作为模型体系。结果表明，铁电材料中的自发极化促进了光激发载流子的分离，从而直接影响光催化活性。此外，为了进一步提高光催化性能，还在BaTiO_3表面附着了银纳米颗粒。
Monodispersed ferroelectric BaTiO3 nanoparticles are synthesized as a model system to investigate the effect of ferroelectricity on a photocatalytic process. The results demonstrate that ferroelectricity can directly affect the photocatalytic activity due to promotion of the separation of photo-excited carriers by spontaneous polarization in ferroelectric materials. Moreover, Ag nanoparticles are attached on these BaTiO3 to further improve the photocatalytic property.
