Abstract
In this study, isopropyl alcohol was used as a solvent, and a sol-gel method was applied to a glass substrate to prepare a zinc oxide-doped aluminum film layer (ZnO, AZO), and then hydrothermally grown yttrium doping. Zinc oxide nanowires (ZnO: Gd NWs), and finally gold-doped yttrium-doped zinc oxide nano-particles (Au-ZnO: Gd NWs) to form photocatalysts for photocatalytic decomposition of methylene blue (MB) in aqueous solution. Various crystal structure analyses were carried out using SEM, EDS, SAED, XRD, PL, Hall, and UV-Vis..
In the photocatalytic measurement section, photo-degradation of methylene blue (MB) was carried out on Gd-doped ZnO nanowires with different parameters at room temperature using a 3 Watt UV-365 nm LED lamp. Then, it was found that the coated aluminum-platinum paper could increase the photocatalytic efficiency. Finally, the use of gold drop on the surface of the test piece facilitated the catalytic reaction of the photocatalyst.
