“…As for the more prominent magnetic materials utilized in recent works, Fe 3 O 4 is an especially prevalent semiconductor, often combined with g-C 3 N 4 in silver-integrated photocatalytic composites, especially for the photodegradation of azo/rhodamine-based dyes [65,[140][141][142][143][144][145][146]. Additionally prominent in such works are several types of spinel ferrites (MFe 2 O 4 ), based on M = Mg [134], Co [20,147], Ni [148], Zn [70,149,150] and even mixed ferrites as Ni 0.5 Zn 0.5 Fe 2 O 4 [151,152].…”

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.

Absorptive materials, by absorbing electromagnetic wave energy, effectively mitigate electromagnetic interference through reduction or elimination of wave reflection. The electromagnetic parameters of materials determine their electromagnetic wave absorption performance. Traditional control strategies, such as adjusting filler ratio, changing macroscopic morphology, and regulating composite methods, have certain limitations to control their structure and cannot fundamentally alter their electromagnetic parameters, which severely hinders their further development. Now, micro-nanostructure design strategies can basically change electromagnetic parameters of the materials by altering their electrical conductivity, charge density and magnetic properties, showing significant advantages in controlling electromagnetic wave absorption capacity. However, the precise micro-nanostructure designand the mass production still face challenges to be overcome. Additionally, structure-property relationship between micro-nanostructures and electromagnetic wave response, and its underline mechanisms are still not fully understood.Herein, a comprehensive review on these relationships was introduced to elucidate the advantages of micro-nanostructure design strategies for regulating electromagnetic wave absorption capacity. Moreover, by introducing these strategies, such as element doping, surface effect modulation and nucleation-controlled growth, this review provides researchers with deep insights and theoretical guidance for modulating electromagnetic properties through micro-nanostructure design. Finally, the research progresses on electromagnetic performance modulation through micro-nanostructure design based on the case of quantum dots, nanocrystals and nanowires, as well as the current research status and prospects in the field of electromagnetic absorption were summarized, providing a theoretical foundation and strategic support for the development of micro-nanoparticles.
