Synthesis and comprehensive characterization of metal oxide nanoparticles for enhanced catalytic performance

Abstract

A facile chemical route was used to produce metal oxide nanoparticles with controlled shape and crystallinity. The synthesised materials were characterised by ultraviolet-visible spectroscopy (UV-Vis). Surface area analysis by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Structural and morphological studies confirmed the successful production of nanoscale mixed metal oxides. The synthesised nanoparticles are found to have various applications, showing strong photocatalytic performance due to their high surface-to-volume ratio enhancing pollutant adsorption and catalytic efficiency under visible light radiation. This strategy illustrates how mixed oxides absorb visible light, generate charge carriers, and efficiently produce reactive radicals that break down pollutants, making them highly effective for photocatalysis in environmental remediation.
