Synergistic oxidation - filtration process analysis of catalytic CuFe2O4 - Tailored ceramic membrane filtration via peroxymonosulfate activation for humic acid treatment

Janus electrocatalytic flow-through membrane enables highly selective singlet oxygen production

“…Fabrication and properties of Pd-Pt-CM. Due to their intrinsic electrical insulating properties and large thickness [35][36][37] , CM can serve as ideal substrates for incorporating both cathodic and anodic electrodes on separate sides of CM. This unique feature allows for sequential electro-redox reactions occurring in different inner-porous CM regions during electrocatalytic filtration.…”

“…7). The smooth surface and hydrophilic nature of the Pd-Pt-CM suggest a lessened fouling potential by organic molecules 35,37 and thus more efficient electron transfer during filtration. Spatiotemporal distribution of 1 O 2 and other ROS in Pd-Pt-CM.…”

Heterogeneous Catalytic Oxidation for the Degradation of Aniline in Aqueous Solution by Persulfate Activated with CuFe2O4/Activated Carbon Catalyst

“…The presence of Fe(II) led to the appearance of these peaks which meant that Fe(III) had conversed to Fe(II) in reaction process. As for Cu2p, Figure 7 d) shows three peaks at binding energy of 934.3 eV for Cu2p3/2, 941.7 eV for satellite peaks, 954.0 eV for Cu2p1/2, [34] indicating the presence of Cu(II) in fresh WAC-30 %. For the XPS spectra of reacted WAC-30 %, the satellite peak of Cu 2p3/2 slightly shifted to lower binding energy value at 741.3 eV, suggesting that the valences of the Cu species had changed and formed a mixture of species.…”

Hybrid oxidation separation technology (HOST) for synergistic removal of recalcitrant pollutants in water

“…• Uniform distribution of CuFe2O4 on the CM surface: Wcat = 0.6 g • CoFe2O4 were also found within the membrane pores (Zhao et al, 2020b) Surface-nucleated heterogeneous crystal growth…”

“…successfully fabricated Fe2O3-coated CCM by alternate deposition of the Fe2O3 colloidal suspension and aqueous phytic acid for effective organic removal and DBP inhibition in the hybrid catalytic ozonation and chloride) (PDDA) layer onto the CM, followed by a layer of negatively charged MnO2 suspension to assemble a MnO2 sublayer onto the CM surface.The final multilayer MnO2 coating was achieved by repeating the alternate layer-by-layer coating of the polycation PDDA and the negatively charged MnO2 suspension. It was reported that the increase of coating times could significantly improve the catalytic performance of the CCM due to more active sites available for the catalytic reactions(Guo et al, 2016).Instead of pre-synthesised MeOx, the CM substrate can be first coated with the MeOx precursor solution via surface coating techniques, such as dip-coating(Wang et al, 2020c) and spin-coating(Zhao et al, 2020b) processes, followed by heat treatment for the MeOx to crystallise and immobilise onto the CM surface. For instance, Chen et al (2015b) fabricated Ti-Mn oxide-coated CCM via a sol-gel technique combined with dip-coating technique and applied for aquaculture wastewater treatment in a pilot scale hybrid catalytic ozonation and membrane separation process.…”
