“…Beside, our previous works also proved that the amounts of different ions on the surface of ferrite catalysts greatly affect their photo-Fenton performance [Ngo TPH and Le TK 2018]. It was observed that the photo-Fenton catalytic activity tends to rise when the surface Fe content of our catalysts gradually increases [Ngo TPH and Le TK 2018] [Silva et al 2020]. These new mixed oxides exhibited both magnetic behavior and high photo-Fenton catalytic activity for the degradation of methylene blue under visible light.…”

“…Figure 5 shows an example of the sol-gel auto combustion method. A modified sol-gel method known as Pechini method has also been referenced in literature [97]: In brief, iron (II) and copper (II) salts were added in an aqueous citric acid solution. After gelation, a suitable amount of ethylene glycol was added, followed by several calcination steps to synthesize efficient and reusable magnetic CuFe nanosized particles because of its numerous advantages such as reproducibility, high ratio of surface to volume products, good stoichiometric control and the production of ultrafine particles with a narrow size distribution in a relatively short processing time at lower temperatures [85,96].…”

In this review, the most recent advances in the field of magnetic composite photocatalysts with integrated plasmonic silver (Ag) is presented, with an overview of their synthesis techniques, properties and photocatalytic pollutant removal applications. Magnetic attributes combined with plasmonic properties in these composites result in enhancements for light absorption, charge-pair generation-separation-transfer and photocatalytic efficiency with the additional advantage of their facile magnetic separation from water solutions after treatment, neutralizing the issue of silver’s inherent toxicity. A detailed overview of the currently utilized synthesis methods and techniques for the preparation of magnetic silver-integrated composites is presented. Furthermore, an extended critical review of the most recent pollutant removal applications of these composites via green photocatalysis technology is presented. From this survey, the potential of magnetic composites integrated with plasmonic metals is highlighted for light-induced water treatment and purification. Highlights: (1) Perspective of magnetic properties combined with plasmon metal attributes; (2) Overview of recent methods for magnetic silver-integrated composite synthesis; (3) Critical view of recent applications for photocatalytic pollutant removal.

Recent Achievements in Dyes Removal Focused on Advanced Oxidation Processes Integrated with Biological Methods

In the last 3 years alone, over 10,000 publications have appeared on the topic of dye removal, including over 300 reviews. Thus, the topic is very relevant, although there are few articles on the practical applications on an industrial scale of the results obtained in research laboratories. Therefore, in this review, we focus on advanced oxidation methods integrated with biological methods, widely recognized as highly efficient treatments for recalcitrant wastewater, that have the best chance of industrial application. It is extremely important to know all the phenomena and mechanisms that occur during the process of removing dyestuffs and the products of their degradation from wastewater to prevent their penetration into drinking water sources. Therefore, particular attention is paid to understanding the mechanisms of both chemical and biological degradation of dyes, and the kinetics of these processes, which are important from a design point of view, as well as the performance and implementation of these operations on a larger scale.
