摘要: Abstract In this study, a new magnetic catalyst for enhancing the ozonation process, named as CFOH, precursor of CuFe2O4 (CFO) was used to enhance ozonation. The comparison surface properties, performance, and reaction mechanisms CFO CFOH in catalytic investigated. showed higher area, pore volume, stronger acidic sites than those CFO. Importantly, both exhibited magnetization, which can be separate catalysts from bulk solution reuse. addition, faster degradation mineralization phenacetin (PNT) by were observed. generation/decay intermediates H2O2 identified studied processes. yield decomposition rate determined concentration OH, found key better activity CFOH. Furthermore, fates benzene- open-ring processes also reactions, including adsorption observed generated PNT oxidation. These reactions became more significant when using catalyst, justifies ability
