Mil-53(Fe) Derived Magnetic Cufe2o4/Fe2o3 Composite For Catalytic Oxidation Of Sulfamethoxazole Via Peroxymonsulfate Activation, Abdul H. Asif, Nasir Rafique, Rajan A. K. Hirani, Lei Shi, Yantao Wang, Xiaoguang Duan, Yu Yin, Hongqi Sun
Research outputs 2022 to 2026
Design of metal–organic framework (MOF) derived metal oxides is an effective approach for environmental remediation. The current study describes the fabrication of MIL-53-derived perforated CuFe2O4/Fe2O3 using a facile, one-step, post-thermal solid-state approach by varying Cu/Fe ratios. Herein, the release of CO2 and H2O during the thermal treatment facilitates the incorporation of Cu2+ onto the Fe2O3 structure, forming a perforated hollow CuFe2O4/Fe2O3 composite via an in-situ ion-exchange mechanism. The optimised catalyst CF-0.5 displays a high degradation efficiency for the removal of sulfamethoxazole (SMX) by heterogeneous activation of peroxymonsulfate (PMS), ascribing to the better textural, morphological, and elemental properties of the novel …

Cobalt Oxide Functionalized Ceramic Membrane For 4-Hydroxybenzoic Acid Degradation Via Peroxymonosulfate Activation, Rajan Arjan Kalyan Hirani, Hong Wu, Abdul Hannan Asif, Nasir Rafique, Lei Shi, Shu Zhang, Zhentao Wu, Lai-Chang Zhang, Shaobin Wang, Yu Yin, Martin Saunders, Hongqi Sun
Research outputs 2022 to 2026
Membrane separation and sulfate radicals-based advanced oxidation processes (SR-AOPs) can be combined as an efficient technique for the elimination of organic pollutants. The immobilization of metal oxide catalysts on ceramic membranes can enrich the membrane separation technology with catalytic oxidation avoiding recovering suspended catalysts. Herein, nanostructured Co3O4 ceramic catalytic membranes with different Co loadings were fabricated via a simple ball-milling and calcination process. Uniform distribution of Co3O4 nanoparticles in the membrane provided sufficient active sites for catalytic oxidation of 4-hydroxybenzoic acid (HBA). Mechanistic studies were conducted to determine the reactive radicals and showed that …
