Investigation of Laser-Based Mo-Doped ZnO Nanoparticle Production and Photocatalysis Application

One of the most sensible, economical, and ecologically friendly methods for treating wastewater is photocatalytic treatment. The most widely used and easily accessible photocatalyst for wastewater treatment is zinc oxide (ZnO). This study used laser ablation to create ZnO, Mo, and Mo-doped ZnO photocatalysts. The nanoparticles were then characterized using linear absorbance, X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The degradation of methylene blue under UV-Vis spectroscopy was used to evaluate the photocatalytic activity of the photocatalysts and the reaction’s kinetics. The Mo doping of ZnO enhanced photocatalytic degradation efficiency, according to the analytical data. This study’s 90 min photocatalytic degradation experiments showed about 94.11% methylene blue degradation efficiency. Mo-doped ZnO nanoparticle photocatalysts have a promising future for treating wastewater, according to this study, which calls for more research in this area.
