A novel magnetic nanoscaled Fe3O4/CeO2 composite prepared by oxidation-precipitation process and its application for degradation of orange G in aqueous solution as Fenton-like heterogeneous catalyst

Catalytic oxidation of organic pollutants in wastewater via a Fenton-like process under the catalysis of HNO3-modified coal fly ash

“…Compared to previous studies, [47][48][49] the modied CFA catalyst (i.e., HFA) is more stable and reusable than the catalysts in other studies, which can be reused 6 times, 47 3 times 48 and 4 times. 49 The slow decay of the catalytic capacity of HFA contributes to the loss of active sites displayed in the form of Fe 2 O 3 on the…”

Evaluation of the Efficiency of Detection and Capture of Manganese in Aqueous Solutions of FeCeOx Nanocomposites Doped with Nb2O5

“…The literature provides various values of magnetic parameters of the composite FeCeO x [ 27 , 28 , 29 ], which is associated with the particle size of iron oxide and its fraction in the composites. With sizes up to tens of nanometers, particles have superparamagnetic characteristics, with large sizes-ferromagnetic properties.…”

A Review Paper on Heterogeneous Fenton Catalyst: Types of Preparation, Modification Techniques, Factors Affecting the Synthesis, Characterization, and Application in the Wastewater Treatment

“…Sharma & Dutta synthesized the catalyst using selenium and studied their optical, morphological and structural properties of Se-doped CuO NPs nanoparticles [63]. Gan et al prepared a catalyst by oxidation, reduction and co-precipitation, and that catalyst exhibits great catalytic ability and efficient reusability performance [94]. The researchers studied the application of prepared catalyst by precipitation and co-precipitation method in the various field like color removal and recalcitrant organic compound degradation.…”

“…The researchers studied the application of prepared catalyst by precipitation and co-precipitation method in the various field like color removal and recalcitrant organic compound degradation. Some examples of dye as model pollutant, and prepared catalyst are Ni1-xZnxFe2O4 and methylene blue [156][157][158] [163], orange G and Fe3O4/CeO2 composite [94], catechol and Fe3O4-CeO2 metal oxide [164], methyl orange and Ni-Fe(C2O4)x [165], Rhodamine B dye and Iron molybdate Fe2(MoO4)3 nanopowders [30], congo red and cobalt-copper oxalate and cobalt oxalate nanofibers [166], Phenol and Fe3O4/MWCNT [167], rhodamine B (RhB) and Al pillared bentonite-Fe3O4 nanocomposites (Fe3O4/Al-B) [168]. Table 5 shows the brief literature survey of previous research work in which catalyst was prepared by precipitation and co-precipitation (PPT and CO-PPT) method.…”
