“…Subsequently, the MnFe 2 O 4 /graphene composite was proved to be superior to pure MnFe 2 O 4 in the degradation of rhodamine B (RhB) [10], NH 3 [11], MB [12], and other organic dyes [13] under visible light irradiation. Luciano et al introduced sand into the MnFe 2 O 4 /graphene composite, which not only enhanced the photocatalytic efficiency of MB degradation under visible light irradiation, but also improved the stability and reusability of the ternary composite photocatalyst [14].…”

The MnFe2O4/BGA (boron-doped graphene aerogel) composite was prepared by hydrothermal treatment of MnFe2O4 particles, boric acid, and graphene oxide. When applied as a photo-Fenton catalyst for the degradation of rhodamine B, the MnFe2O4/BGA composite yielded a degradation efficiency much higher than the sum of those of individual MnFe2O4 and BGA under identical experimental conditions, indicating a strong synergetic effect established between MnFe2O4 and BGA. The catalytic degradation of rhodamine B was proved to follow pseudo first-order kinetics, and the apparent reaction rate constant on the MnFe2O4/BGA composite was calculated to be three- and seven-fold that on BGA and MnFe2O4, respectively. Moreover, the MnFe2O4/BGA composite also demonstrated good reusability and could be reused for four cycles without obvious loss of photocatalytic activity.

“…Carbon nanomaterials have been viewed as a very interesting potential material for the generation of novel nanocomposites due to both the availability of the starting material and their interesting properties ( Table 5). An interested effect was reported by Yamaguchi et al [93] who reported the synthesis of a composite of manganese ferrite (MnFe 2 O 4 ) particles (average size, 200 nm) supported by graphene oxide and sand through a solvothermal process. These composites with particles of approximately 200 nm in size demonstrated effective degradation of methylene blue in the presence of light and H 2 O 2 through the Fenton reaction.…”

Water resources are of extreme importance for both human society and the environment. However, human activity has increasingly resulted in the contamination of these resources with a wide range of materials that can prevent their use. Nanomaterials provide a possible means to reduce this contamination, but their removal from water after use may be difficult. The addition of a magnetic character to nanomaterials makes their retrieval after use much easier. The following review comprises a short survey of the most recent reports in this field. It comprises five sections, an introduction into the theme, reports on single magnetic nanoparticles, magnetic nanocomposites containing two of more nanomaterials, magnetic nanocomposites containing material of a biologic origin and finally, observations about the reported research with a view to future developments. This review should provide a snapshot of developments in what is a vibrant and fast-moving area of research.

“…With the current global economic evolution, tackling prominent pollutants has become a global priority (Abdel Maksoud et al 2020;Makvandi et al 2021;Mamba et al 2007;Singh et al 2021). Hence, a variance of approaches has been undertaken to promote techniques for removing or decomposing pollutants, such as adsorption (Xiao et al 2020), membrane separation (Luciano et al 2020), biological (Oliveira et al 2020), coagulation (Sillanpää et al 2018), photo-oxidation (Onga et al 2020), and photocatalysis technologies (Chenab et al 2020).…”

The world is currently facing critical water and energy issues due to the growing population and industrialization, calling for methods to obtain potable water, e.g., by photocatalysis, and to convert solar energy into fuels such as chemical or electrical energy, then storing this energy. Energy storage has been recently improved by using electrochemical capacitors and ion batteries. Research is actually focusing on the synthesis of materials and hybrids displaying improved electronic, physiochemical, electrical, and optical properties. Here, we review molybdenum disulfide (MoS2) materials and hybrids with focus on synthesis, electronic structure and properties, calculations of state, bandgap and charge density profiles, and applications in energy storage and water remediation.
