Preparation and characterization of layered perovskite La2Ti2O2 by ultrasonic spray pyrolysis |
| 초록 |
Monoclinic compound La2Ti2O7 with [100] layered perovskite structure, has been reported to have good photocatalytic activity in water splitting reaction under uv-visible region. La2Ti2O7 was usually synthesized by the typical solid-state reaction. As the result of this synthsesis method, It is difficult to obtain a high homogeneity and large specific surface area and control a morphology of layered perovskite material. Therefore, In this study, we synthesized La2Ti2O7 with ultrasonic spray pyrolysis to improve its properties. It was compared with La2Ti2O7 prepared by solid state reaction and polymerized complex method by a crystallinity, morphology and optical property.
