Mn3O4 Catalysts for Advanced Oxidation of Phenolic Contaminants in Aqueous Solutions

Water-soluble organic pollutants, such as phenolic compounds, have been exposed to environments globally. They a significant impact on groundwater and surface water quality. In this work, different Mn3O4 catalysts were prepared for metal oxide activation of peroxymonosulfate (PMS) remove the compound from environment. The as-prepared characterized using thermogravimetric-differential thermal analysis (TG-DTA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) area analysis. Furthermore, effect temperature reusability is also investigated. nanoparticles (NPs) catalyst reveals an excellent performance activating PMS phenol compounds. NPs exhibits 96.057% efficiency in removing 25 ppm within 60 min. kinetic shows that fitted into pseudo-first order model exhibited relatively low energy 42.6 kJ/mol. test displays exceptional stability with 84.29% after three-sequential cycles. proven suitable remediation aqueous solutions.
