Enhanced photocatalytic activity of Ce-doped β-Ga2O3 nadnofiber films fabricated by electrospinning method |
| 초록 |
In the present study, we fabricated Ce-doped β-Ga2O3 catalysts synthesized by a sol-gel derived electrospinning and subsequent calcination. The electrospun nanofiber films were characterized by using a scanning electron microscopy (SEM), UV/Vis spectrophotometer, X-ray diffraction (XRD), and photo-degradation analyses. It is notable that Ce doping affects the morphology, crystallinity, optical band gap energy, and finally photo-degradation ability. For photo-degradation, the highest degradation kinetic constant (k) was obtained from 0.7 mol% doped β-Ga2O3 nanofiber films. Therefore, it can be concluded that the degradation of MB under UV radiation was more efficient with the Ce-doped β-Ga2O3 nanofiber films than with un-doped β-Ga2O3 nanofiber films. |
