Magnetic ordered mesoporous copper ferrite as a heterogeneous Fenton catalyst for the degradation of imidacloprid

Green and chemical-engineered CuFe2O4: characterization, cyclic voltammetry, photocatalytic and photoluminescent investigation for multifunctional applications

“…After that, a lot of superoxide radicals (O 2•− ) and hydroxyl radicals (OH • ) are formed. These produced active radicals react with the ionized MG molecules to decompose them into the harmless H 2 O, CO 2 , and mineral acids (NO 2− , NO 3− , or SO4 2− ) [37,[41][42][43][44]; during this step, partial strong oxidizing holes (h +) can also directly participate in the decomposition of the MG molecules. According to the results obtained, the self decomposition of MG molecules is very negligible.…”

Multiwalled carbon nanotube-supported CuCo2S4 as a heterogeneous Fenton-like catalyst with enhanced performance

“…The iron-based bimetal catalysts such as CoFe 2 O 4 and CuFe 2 O 4 showed high catalytic efficiencies with an increased activity of Fe 2 O 3 but were limited by the narrow applicable pH range of Fe 2+ . 17,18 Moreover, copper and cobalt catalysts have been studied separately, but the combined effect of copper and cobalt in the Fenton reaction has not been studied. 19,20 Thus, we drew our attention on their bimetal suldes.…”

Fe/Cu mesoporous carbon supported alumina hollow ceramic membrane for the degradation of ofloxacin

“…As illustrated in Fig.4b, compared with the bimetallic Fe/Cu mesoporous carbon active layer, the degradation of ofloxacin by the single metal iron mesoporous carbon activated layer ceramic membrane was significantly decreased by 50 %. It is indicating that the Fe(III) and Cu(II) on the surface of the active layer could catalyze H 2 O 2 decomposition to generate ·OH radicals [3] (Wang, Zhao et al 2013), and the synergistic effect of Fe and Cu also could promote the decomposition of H 2 O 2 and produce more ·OH radicals, which increased the degradation rate. …”
