Synthesis And Characterization Of Cu1-Xnixo/Fe2o3 Composite From Plant-Mediated Ni-Doped Cuo And Fe2o3 For Degradation Of Methylene Blue

Abstract

Water Pollution Is A Widespread Serious Environmental Issue That We Face On A Global Scale. The Increased Demand For Clean Water Amplified The Importance Of Removing Toxic Organic Pollutants From Wastewater Sources. These Toxic Chemicals Can Be Transformed Into Non-Toxic Substances By Degradation Using A Photo Catalytic Process. For This, Different Oxide Materials Have Been Used. Among These Materials, Copper Oxide (Cuo) Is One Of The Most Widely Used Oxide For The Degradation Of Methylene Blue (Mb) Organic Dye Molecules From Wastewater. However, There Are Challenges With The Usage Of Cuo For Photo-Catalysis Such As Charge Carrier??S Recombination Which Resulted In Lowering The Degradation Efficiency. To Overcome This Problem, Acmella Ciliate Plant-Mediated Ni-Doped Cuo Was Synthesized And A Composite Was Formulated, I.E., Cu1-Xnixo/Fe2o3 (X = 0.01, 0.02, 0.03, 0.04). The Samples Were Subjected To Characterizations Such As X-Ray Diffraction (Xrd), Thermo-Gravimetric Analysis (Tga), And Fourier-Transform Infrared (Ftir).Scanning Electron Microscopy (Sem), Brunauer Emmett-Teller (Bet), Photoluminescence (Pl),Electrochemical Impedance Spectroscopy (Eis), And Uv- Vis Spectroscopy Have Been Used. The Optical Bandgap Of The Synthesized Cuo, 2nco, Fe2o3, And (60%) 2nco/40%Fe2o3 Was Found To Be 2.2, 2.17, 2.3, And 1.7 Ev, Respectively. The Absorbance And Degradation Performance Of Ni Doped Cuo Against Mb Was Analyzed And The 2% Ni-Doped Cuo Yielded An Optimum Result. Therefore, The 2% Ni-Doped Cuo (2nco) Was Further Used For The Establishment Of A Composite With Fe2o3. The Nominal Composition Of The Oxide Composite Was (1-X) 2nco/(X) Fe2o3 (X=0.1,0.2, 0.3, 0.4, And 0.5). The Degradation Performance Of These Oxide Composites Was Determined Against Mb And The Sample With The Nominal Composition Of (60%) 2nco/40%Fe2o3 Resulted InAn Optimum Degradation Percentage Of 94%. The Recyclability Test Was Performed For 5 Cycles Using The (60%) 2nco/40%Fe2o3 And The Sample Remained Stable. Therefore, According To The Present Finding, The Plant-Mediated Ni-Doped Cuo And Fe2o3 Materials Systems Can Degrade Mb Organic Dye From Industrial Effluents.
