Title : Development of multifunctional catalyst for removal of persistence compounds


Optical property of ZnO enhanced through Fe-doped ZnO nanoparticles synthesis through precipitation method using Zinc acetate dihydrate as a precursor and Oxalic acid as a bridging agent dissolved in alcohol. For optimum enhancement of catalyst, reflux method add-on with precipitation method. Optimization of amount of dopant by preparing Fe-doped ZnO in (0.5, 0.75, 1.0, 3.0, and 5.0 wt.%). Characterization of study of prepared Fe-doped ZnO nanoparticles reveals that, 5 wt.% Fe doped ZnO gave best result of bandgap reduction as compared to rest. The FT-IR and XRD data reveals that with 1:3 %wt. ratio of Zinc Acetate Dihydrate: Oxalic acid ratio gives the optimized result among various other ratio such as 1:1, 1:2, 2:1, 2:3, 1:3. FT-IR data reveals that ZnO nanoparticles prepared with 1:3 ratio shows peak at 637 nm-1, While XRD data reveals that ZnO nanoparticles prepared with same ratio forms wurtzite structure nanoparticles. Photocatalytic degradation study of organic wastewater conducted between Bare ZnO and Fe-doped ZnO under the LED and Solar light source. Reduction in Bandgap from 3.17 eV of bare ZnO to 2.68 eV of Fe-doped ZnO reveals that Fe-doped ZnO has more tendency to work under visible light source.
