CoMn2O4 (CMO) has been recognized as an effective peroxymonosulfate (PMS) activator; however, it still shows disadvantages such limited reactive sites and metal leakage. Herein, environmentally friendly composite catalyst, CMO/Kln, was synthesized by anchoring CMO on kaolinite (Kln), a natural clay mineral with special lamellar structure, to activate for the degradation of residue pharmaceuticals in water. The abundant hydroxyl groups located surface Kln helped induce rich oxygen vacancies (OVs) into which not only acted additional active but also accelerated working efficiency. In addition, compared bare CMO, CMO/Kln showed lower crystallinity, adoption substrate contributed its structural stability leaching after three rounds reaction. universal applicability verified using other probes. This work shed light minerals modifying catalysts promoted catalytic activity efficient eco-friendly remediation wastewater.

Abstract FeMnOx@TiO2 core-shell catalysts with different shell layer thicknesses were prepared by co-precipitation method to investigate the effect of thickness on activity and stability catalyst for low-temperature denitrification. It was found that NOx removal efficiency 60% (FM@T60) content above 98% between 160 320 °C. The physicochemical properties investigated analyzed characterization means such as XRD, BET XPS, H2-TPR. TiO2 in FM@T60 effectively mitigated toxic SO2, provided a large specific surface concentrated pore size distribution facilitated adsorption-desorption reaction catalyst. number acidic sites improved NH3 adsorption performance. abundant active components Mn3+, Fe3+ high proportion chemisorbed oxygen promoted electron migration conversion interface, which enhanced redox capacity synergistic interaction core its NH3-SCR sulfur resistance.
