Abstract: In the present study different metal oxide nanoparticles (Magnesium, Zinc and Copper) were synthesized using two different methods wet chemical method and hydrothermal method. These nanoparticles were characterized using FESEM, EDAX and XRD to investigate their structural and morphological properties. Their potential for dye degradation is experimentally verified. XRD data was used to calculate the particle size using Debye Scherrer formula and it was found to be in the nano-range. SEM analysis also supported that metal oxide particles are in the nano-range with varying morphology. EDAX confirms the presence of metals Zn, Mg and Cu in the respective oxides.
