The Influence of Manganese Doping on Zinc Oxide Nanoparticles for Photocatalytic Degradation of Methylene Blue Dye

Abstract

Successful scalable synthesis of Manganese-doped and Pure Zinc oxide nanoparticles (3%, 5%, 7% Mn-ZnO) utilizing a straightforward and cost-efficient combustion method has been done. Once synthesized, the samples were analyzed using X-ray Diffractometer (XRD) to unveil their crystal and lattice parameters, while UV-Vis DRS Spectroscopy will shed light on their optical properties. To further understand their physical characteristics, both the pure and doped nanoparticles will undergo scrutiny via FE-SEM, Energy Dispersive X-ray (EDX) and X-ray Photoelectron Spectroscopy (XPS), techniques. In the next phase, doped nanoparticles were employed as photocatalysts, specifically for photodegradation of Methylene Blue (MB) dye under visible light exposure, with the resulting changes being analyzed using UV-Vis Spectroscopy. Furthermore, parallel experiments were conducted with the presence of an oxidizing agent, Hydrogen Peroxide (H₂O₂), facilitating a comprehensive comparative analysis. This approach promises valuable insights into both the properties of these nanoparticles and their potential applications.
