Hydrothermal synthesis of Cr and Fe co-doped TiO2 nanoparticle |
| 초록 |
We report here the new findings on the visible light photodecomposition activity of gaseous iso-propyl alcohol over Cr and Fe co-doped TiO2 nanoparticles. High surface area, doped TiO2 nanoparticles were synthesized hydrothermally and co-dopant effects are investigated. The physico-chemical properties of the co-doped nanoparticles led to efficient photocatalysts. Cr and Fe co-doped TiO2 nanoparticles exhibited two times higher photocatalytic activity for photodecomposition of gaseous isopropyl alcohol than the individually (Cr/ Fe) doped TiO2 nanoparticles under visible light irradiation (λ＞420nm). The activity is mainly correlated to the larger absorptions around 496nm and 563nm wavelengths by co-doped TiO2 nanoparticles than Fe doped TiO2 nanoparticles those possibly absorb ≤ 496nm. |
