Bimetallic Cu/Fe Catalysts for Ibuprofen Mineralization

At present, the use of conventional wastewater processes is becoming increasingly challenging, mainly due to presence biorecalcitrant organic matter. Advanced oxidation such as Fenton, Fenton-like and hybrid have been successfully employed for treatment highly concentrated toxic non-biodegradable pollutants. Here, a series bimetallic catalysts, based on Cu/Fe supported over ZrO2, were investigated mineralization ibuprofen with heterogeneous reaction. The materials prepared by incipient wetness impregnation characterized standard techniques. Temperature-programmed experiments highlighted promotion reduction in CuO synergistic effects coupled redox cycles copper (Cu2+/Cu+) iron (Fe+3/Fe+2). 5%Cu-5%Fe/ZrO2 not only displays highest (83%) under optimum conditions but also exploits its activity wider range pH (3–5) extremely low metal leaching. recycling catalysts reveals that system able provide sustainable Fenton process.
