| 제목 | Photocatalytic properties and electronic structure of Ca2Nb2O7 layered perovskite material |
| 초록 | Among various methods of solar energy conversion, much attention has been paid to the photocatalytic water splitting for its potential significance in obtaining directly clean and high energy containing H2 from abundant H2O. The perovskite materials such as SrTiO3 and CaTiO3 have photocatalytic activities for water splitting under UV light irradiation. However, the quantum yields are very low (ca. ＜1%). Thus there is need to explore the photocatalytic properties of newer materials. In this paper, we report the photocatalytic properties of highly donor-doped (110) layered perovskite material, Ca2Nb2O7, along with its electronic band structure calculations. We further discuss the experimental and theoretical results in light of the photocatalysis. The photocatalytic and electronic properties indicate Ca2Nb2O7 to be a better photocatalyst than conventional or other known candidates viz. TiO2, SrTiO3, BaTiO3. |
