ENHANCED PHOTO-DEGRADATION ACTIVITY OF HYBRID ZnMgTiO2 NANOCOMPOSITES AGAINST METHYL ORANGE DYE UNDER UV IRRADIATION

The main focus of this research is to study the role and effect of magnesium, titanium composites on the optical, morphological and structural properties of ZnO nanoparticles. Hybrid nanocomposites of ZnO has been successfully synthesized by soft chemical method using zinc nitrate hexahydrate, magnesium nitrate hexahydrate, titanium isopropoxide and sodium hydroxide. The structural characterizations were done by powder XRD and FT-IR shows the ZnO nanoparticles are polycrystalline with a standard hexagonal ZnO wurtzite crystal structure and the respective decrease in particles size shows that increases the percentage of TiO in the ZnO crystal lattice. The morphology of the composite ZnO nanoparticles has been determined by SEM. The UV-VIS absorption analysis depicted that all the samples exhibit the absorption in the visible region also increases with change in concentration of the dopants. In addition with this the Photo degradation activity of all the synthesized hybrid nanocomposites were tested against methyl orange dye. The ZnMgTiO2 was emerged as a better Photo-degradation activity when compared to pure ZnO and Mg doped ZnO samples.
