Pivotal roles of MoS2 in boosting catalytic degradation of aqueous organic pollutants by Fe(II)/PMS

Photocatalytic Advanced Oxidation Processes for Water Treatment: Recent Advances and Perspective

“…Currently, there are many ways to achieve the activation of PS and PMS, such as ultraviolet rays, heat, high pH environment or the presence of transition metals (Fe, Co, Cu). [54,55] Figure 5 shows the activation mechanism of PMS. Photocatalysts activated by transition metals have the advantages of cost effectiveness and environmental friendliness as the activators of sulfates.…”

“…Photocatalysts have a longer service life because they can be recycled through redox cycling and are easy to separate from the treated water. [55,57] At the same time, the secondary treatment of metals dissolved in the treated water is avoided. Unlike * OH, the electrophilic sulfate radical is more likely to react with electron-giving groups, such as amino, hydroxyl, alkoxy, aromatic constituents, and other unsaturated compounds, making the radical selective for oxidative degradation ability.…”

MoS2-based nanocomposites: synthesis, structure, and applications in water remediation and energy storage: a review

“…Among the family of transition metal dichalcogenides, molybdenum disulfide (MoS 2 ) has recently been broadly studied in many research fields such as: lubrication, supercapacitors, lithium-ion batteries and drug delivery, because of its extraordinary activity and its perfect two-dimensional structure. MoS 2 has also exhibited excellent performance in environmental remediation applications such as electroor photocatalysis, adsorption of heavy metals, ammonium nitrogen removal, and membrane-based separation (Kalin et al 2012;Lin et al 2015;Chang et al 2016;Wang and Mi 2017;Zhang et al 2017a;Fan et al 2019;Liu et al 2018a;Xing et al 2018;Sheng et al 2019;Zhou et al 2020).…”

MoS2-assisted Fe2+/peroxymonosulfate oxidation for the abatement of phenacetin: efficiency, mechanisms and toxicity evaluation

“…19 Simultaneously, previous studies have also proved that MoS 2 , as a co-catalyst, can be recycled and reused. [20][21][22] Therefore, the MoS 2 -assisted Fe 2+ /PMS oxidation process is a promising method to apply to PPCPpolluted water.…”
