FABRICATION OF SELF-CLEANING GLASS BY ZnO@rGO PHOTOCATALYTIC THIN FILM ONRIENTED 1D NANOROD ARRAY ON THE GLASS SUBSTRATE.

Abstract

In this study, crystal nanorod array ZnO@rGO thin film on the glass substrate was synthesized via hydrothermal and nuclei crystalline implant method. According to this, ZnO crystalline nanorod arrays were first grown onto the glass substrate. And then, to improve the applicable performance of the film, rGO material which subsequently anchor to the ZnO film was synthesized by using the modified Hummer’s method. The as-synthesized crystal nanorod array ZnO@rGO thin film oriented on the glass substrate one dimension (1D) was characterized by physical chemical techniques such as x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM). Performance of the film applied in the photocatalytic reaction through methylene blue degradation that was evaluated by the UV-Vis. As the results, the ZnO@rGO film is oriented on the glass substrate as 1D and well-array as well with 50 nm in diameter, around 1-2 µm and wurtzite cryatal. The XRD and TEM results reveal the evidents of the composited ZnO@rGO film formed on the glass substrate. On the other hand, the UV-Vis analysis shows the MB degradation reaction photocatalytic performance of the ZnO@rGO film is dominated as comparing with the ZnO and ZnO@GO one.
