Emerging Materials in Advanced Oxidation Processes for Micropollutant Treatment Process

Advanced oxidation processes (AOPs) for micropollutant treatment have proved to be efficient and cost-effective techniques because of possessing features like high oxidation performance and no subsequent pollution. Besides, these processes have been used to effectively degrade certain classes of new contaminants that conventional technology cannot handle. Further, emerging complex contaminations require a more advanced material composition for their degradation. Various emerging materials used in AOPs include graphene, solid pyrite, FeCuC, nickel–zinc ferrite composite material, BiFeO₃ magnetic nanoparticles, Fe-TiO₂/activated carbon (AC), Fe₃O₄/TiO₂/reduced graphene oxide (RGO), 2Fe-CeO₂ catalyst, Fe-TiO₂/AC (FTAC), CuO/Cu₂O/Cu, graphitic carbon nitride (g^_C₃N₄)^_Bi₂O₂CO₃, SiC^_B₂iO₂CO₃, Mn₂O₃/AC, CuO_x/granular activated carbon (GAC), Fe–Mn–O nanosheets/wood carbon, iron ore tailings, Fe₂O₃/NaHSO₃, FeNi₃/SiO₂/ZnO, Fe₃O₄, WO₃/bucky paper membrane, peracetic acid and Fe(II), bentonite/TiO₂/Ag, Fe₃O₄ nanoparticles, Fe@Fe₂O₃/active carbon fiber (ACF), FeNi₃/chitosan/BiOI, Ag-CuFe₂O₄@WO₃, carbon nano tubes (CNTs), TiO₂/CNT, Fe/CNT, persulfate (PS)/Cu^o, PS/Cu^o/ultrasound (US), PS/Fe⁰/US, periodate and its composites, nanocomposites of MXene, Ti₃C₂, (ti₃C₂T_x) MXene, ZnO/Ti₃C₂T_x, etc. This chapter presents a comprehensive overview of the characteristics of emerging materials of distinct AOPs and their prospective advancements in improving micropollutant treatment efficiency.
