“…Cobalt, cerium, manganese, copper, and another redox metal oxides were utilized as catalysts to investigate their reactivity to H 2 O 2 degradation into cOH in the Fenton-like degradation of organic pollutants. [212][213][214][215] Cerium oxides (CeO 2 ) (such as CeO 2 nanorod and CeO 2 nanocube) as heterogeneous Fenton-like catalysts have been attracted great interest for their catalytic oxidation applications. 216 Additionally, Ce-doped MOF and CuO/Al 2 O 3 are also efficient heterogeneous Fenton-like catalyst with high activity in Fenton-like oxidation of hazardous pollutants.…”

“…ese effluents are difficult to be treated because of its high concentration on dyes, which have a synthetic origin and a complex molecular structure that makes them more stable and hardly biodegradable [8]. Several studies list the numerous impacts of dyes on the environment and human health [9][10][11] and the necessity of their removal from colored wastewater before its discharge [12][13][14]. Methylene blue (MB) is a good representative of cationic azo dyes, which does not decompose under ambient conditions and is usually resistant to classical biological treatment.…”

The photo-Fenton oxidation process was employed to degrade methylene blue (MB) using a hydroxide sludge/hydrochar-Fe composite as a catalyst prepared by physical activation of raw hydroxide sludge from a drinking water treatment plant and hydrochar-Fe prepared by hydrothermal carbonization from two-phase olive mill waste. The prepared composite was characterized by XRD, SEM, EDS, ICP, and FT-IR. The effect of major parameters, including pH, H2O2 concentration, and a dose of composite on the removal of MB has been studied. The results indicated that the MB decolorization rate increased with the increase of H2O2 concentration and catalyst addition; however, further increase in H2O2 concentration and catalyst dosage could not result in an increase of MB removal efficiency. A high degradation of 95% was achieved within 150 min under UV light irradiation at natural pH (pH = 5), a catalyst loading of 2.5 g/L, a H2O2 dosage of 14.68 mol/L, and MB concentration of 50 mg/L. Recycling studies show a MB decolorization of 92% after three cycles and the use of the composite for the degradation of another dye (methyl orange) shows a degradation of 99%, demonstrating that this composite is a promising heterogeneous photo-Fenton catalyst for long-term removal of dyes from industrial wastewater.

“…In order to overcome these disadvantages, iron was either complexed with organic molecules, impregnated in different solid catalysts (zeolites, porous carbon and clays) (Gonzalez-Olmos et al 2011;Hassan and Hameed 2011;Fida et al 2017;Lan et al 2020;Long et al 2020;Zárate-Guzmán et al 2020;Zhang et al 2020), or used in oxide form such as goethite (FeOOH), magnetite (Fe3O4) and hematite (Fe2O3) (Hassan and Hameed 2011;Sebatini et al 2020;Bilińska et al 2020;Tang et al 2020). Furthermore, materials based on other transition metals were used as heterogeneous Fenton-like catalysts such as metal oxides, metalphosphates and MOFs (Roumila et al 2016;Zhou et al 2020;Dong et al 2021).…”

Hydroxyapatite (HA), a calcium hydroxyphosphate was prepared via precipitation method and used as a catalyst in a Fenton like process for methyl violet (MV) dye degradation. This study is aimed to evaluate the effect of hydrogen peroxide concentration, HA dose, initial pH, temperature and MV concentration on the catalyst performance to find out the optimum conditions leading to maximum efficiency of the Fenton process. The results showed that MV dye with a concentration of 20 mg L-1 can be removed within just 10 minutes at the optimal conditions of 36 mmol L–1 H2O2 and 2.5 g L–1 HA at pH of 6.65 and T = 48 °C). The experimental outcome of this study also demonstrates that HA displayed a good recyclability over three cycles; while the use of scavenger highlighted that the hydroxyl radical HO• was the main active species for MV degradation. The catalytic tests result of MV dye degradation were analyzed by the first-order, second-order and Benhnajady-Modirshahla-Ghanbery (BMG) kinetic models, those showing that the Fenton like reaction follows the first-order and BMG models. The activation energy of the reaction and the values of thermodynamic parameters such as standard enthalpy (ΔH*0), entropy (ΔS*0) and Gibbs free energy (ΔG*0) were also evaluated. Those results revealed that the degradation of MV over the as-synthesized material is an endothermic and non-spontaneous process.
