Multicomponent Cu-Mn-Fe silica supported catalysts to stimulate photo-Fenton-like water treatment under sunlight

Removal of contaminants emerging concern (CEC) from water is a serious problem. Using sunlight to assist in this process one the most sustainable methods for treatment. In study, we demonstrate that tailoring morphology and optimizing metal concentration multicomponent catalysts through an appropriate synthetic strategy leads Fenton-like photo-Fenton-like systems capable effectively degrading bisphenol A coumarin as model endocrine disruptors probe •OH detection. Multicomponent Cu-Mn-Fe silica supported were prepared via direct synthesis by incorporating magnetic Fe3O4 nanoparticles, Mn Cu during formation nanoparticles with interparticle mesoporosity. Comprehensive characterization advanced microscopic spectroscopic techniques revealed qualitatively quantitatively presence Fe oxides covered support, isolated cations/oxo species into framework CuO particles attached framework. The activities are due catalytic disproportionation H2O2 Cu2+ support. investigated efficient concerning homolytic cleavage hydroxyl radicals, further positive effect radical observed under visible-light illumination thus acting catalysts. properties used easy separation catalyst/photocatalyst after reaction do not contribute catalytic/photocatalytic performance.
