Study on Photocatalytic Degradation of Phenol by ZnO Thin Films

Article Preview

Abstract:

ZnO thin films with excellent properties have been prepared on glass substrates and quartz substrates by sol-gel process. Structural features, surface morphology and UV absorption spectrum have been studied by XRD, AFM and UV-Vis-Nir scanning spectrophotometer. The influence of different wavelengths of UV irradiation, different substrates and different annealing temperature on photocatalytic performance have been further studied. The results show that the ZnO thin films prepared on quartz substrates, annealing at 400 oC has higher degradation rates. The experiments realize the supported catalysts, easy recycling and good catalytic effect.
