Abstract: | MgO nanoparticle was synthesized by precipitation method where MgCl2 .6H2 O, NaOH, C2 H5 OH and urea were used as precursor. Characterization of the prepared photocatalyst were done by XRD, FTIR, SEM, and TEM analyses. Cubic crystalline phase (JCPDS card no.45-0946) and average nanocrystalline size (58 nm) was determined by XRD. The SEM of the MgO nanoparticles revealed the agglomerated spherical roughness morphology with size of 81 nm. TEM of the MgO nanoparticles showed microcrystalline aggregated nearly spherical structure with average size of 78 nm. FTIR spectra of MgO showed clear bands of Mg-O and CO2 bonds. Similarly, bands of CO3 -- and –OH were also observed. The prepared MgO photocatalyst showed 87% of the Methyl orange degradation by using H2 O2 in 210 min. The optimum catalyst dose was found to be 0.1 g for 100 mL of 10 ppm dye concentration for the prepared catalyst. Keywords: MgO, photocatalyst, photocatalytic degradation |
