“…Therefore, it was important to use a catalyst dose of 30 mg as the optimal amount for the photocatalytic degradation process. Generally, increasing the catalyst load leads to an increase in the number of surface-available active sites (Fe 2+ / 3+ ions), and thereby, the dynamic generation of active radicals on the catalyst surface [ 60 ].…”

A magnetite chlorodeoxycellulose/ferroferric oxide (CDC@Fe3O4) heterogeneous photocatalyst was synthesised via treated and modified cotton in two steps. The designed nanocomposites were characterised by FTIR, TGA, XRD, SEM, and VSM analyses. The Fenton-photocatalytic decomposition efficiency of the synthesised magnetic catalyst was evaluated under visible sunlight using Methyl Orange (MO) as a model organic pollutant. The impacts of several degradation parameters, including the light source, catalyst load, irradiation temperature, oxidant dose, and pH of the dye aqueous solution and its corresponding concentration on the Fenton photodegradation performance, were methodically investigated. The (CDC@Fe3O4) heterogeneous catalyst showed a remarkable MO removal rate of 97.9% at 10 min under visible-light irradiation. (CDC@Fe3O4) nanomaterials were also used in a heterogeneous catalytic optimised protocol for a multicomponent reaction procedure to obtain nine tetra-substituted imidazole derivatives. The green protocol afforded imidazole derivatives in 30 min with good yields (91–97%) at room temperature and under ultrasound irradiation. Generally, a synthesised recyclable heterogeneous nano-catalyst is a good example and is suitable for wastewater treatment and organic synthesis.

“…Furthermore, another technique which is as significant as the first entails crosslinking the heterogeneous Fenton catalyst with the polymeric material using crosslinking agents; this leads to anchoring the catalyst within the polymer matrices [44]. In this regard, various crosslinking agents are employed such as glutaraldehyde [45], acrylate [46], and polyethylene glycol [47]. The third method is the incorporation of iron or iron oxide as a heterogeneous Fenton catalyst directly during the synthesis of the polymer.…”

Materials based on polymer hydrogels have demonstrated potential as innovative Fenton catalysts for treating water. However, developing these polymer-supported catalysts with robust stability presents a significant challenge. This paper explores the development and application of polymer-supported heterogeneous Fenton catalysts for the environmental remediation of wastewater, emphasizing the enhancement of metal incorporation into catalysts for improved efficiency. The study begins with an introduction to the heterogeneous Fenton process and its relevance to wastewater treatment. It further delves into the specifics of polymer-supported heterogeneous Fenton catalysts, focusing on iron oxide, copper complexes/nanoparticles, and ruthenium as key components. The synthesis methods employed to prepare these catalysts are discussed, highlighting the innovative approaches to achieve substantial metal incorporation. Operational parameters such as catalyst dosage, pollutant concentration, and the effect of pH on the process efficiency are thoroughly examined. The catalytic performance is evaluated, providing insights into the effectiveness of these catalysts in degrading pollutants. Recent developments in the field are reviewed, showcasing advancements in catalyst design and application. The study also addresses the stability and reusability of polymer-supported heterogeneous Fenton catalysts, critical factors for their practical application in environmental remediation. Environmental applications are explored, demonstrating the potential of these catalysts in addressing various pollutants. The Conclusions offers future perspectives, underlining the ongoing challenges and opportunities in the field, and the importance of further research to enhance the efficacy and sustainability of polymer-supported heterogeneous Fenton catalysts for wastewater treatment.

“…The results revealed that the magnetite nanoparticles can be used as a promising catalyst, and under optimal reaction conditions, over 85% phenol and 100% dye could be removed. The degradation of olive mill wastewater (the physicochemical characteristics of the tested wastewater: pH: 5.02 ± 0.01, COD: 1673 ± 50, OD: 1432 ± 50) compounds by [GTA-(PDA- g -DAC)@Fe 3 O 4 ] developed by Mehdaoui et al 107 exhibited good performance. The effective degradation rates of total phenolic compounds (TPC), total amino compounds (TAC) and chemical oxygen demand (COD) were 89.88%, 92.75% and 95.66%, respectively, after an optimized acoustic heterogeneous catalytic Fenton process.…”
