Abstract	Magnesium oxide (MgO) nanoparticles were prepared using a straightforward Flame Synthesis technique, and their photocatalytic potential against methylene blue (MB) dye was examined. XRD, UV-visible spectroscopy, FESEM, and EDX analysis are used to characterize the produced samples. MgO contains pure cubical phases, according to XRD measurements. FESEM study reveals that pure MgO nanoparticles have irregular, nanocubical, and nanoclustered morphologies. The prepared sample is free of contaminants according to the EDX data. A red shift in the wavelength-dependent absorbance curve was verified by UV–visible spectroscopy analysis. It is shown that MgO degrades MB with an efficiency of 88%.
