Controllable incorporation of oxygen in MoS2 for efficient adsorption of Hg2+ in aqueous solutions

Fabrication of Ultrathin MoS2 Nanosheets and Application on Adsorption of Organic Pollutants and Heavy Metals

“…Meanwhile, the as-prepared MoS 2 NS also displayed more excellent adsorption performance on heavy metals than the bulk MoS 2 . All the results indicated that the exfoliation was beneficial to improve the adsorption performance of MoS 2 , which was in accordance with previous studies [3,36,37].…”

“…Meanwhile, the as-prepared MoS2 NS also displayed more excellent adsorption performance on heavy metals than the bulk MoS2. All the results indicated that the exfoliation was beneficial to improve the adsorption performance of MoS2, which was in accordance with previous studies [3,36,37]. In addition, to well study the adsorption behavior, the Langmuir and Freundlich models were employed to fit the experimental data (Figure 6a,b, Figure S1).…”

Water dissociation and association on mirror twin boundaries in two-dimensional MoSe2: insights from density functional theory calculations

“…However, the catalytic performance of ORR on these defects, which is critical for catalysis, has not been investigated so far. Moreover, the dissociation/association of water molecules and the behavior of their derivatives (hydroxyl groups and isolated O/H atoms) on TMDs with MTBs has not been addressed, contrary to that on basal planes and edges, [42][43][44] while knowing the energetics of these processes is important not only for assessing the catalytic properties but also for understanding the stability of TMDs at ambient conditions and clustering of water molecules at the surface. 45 Here, using rst-principles calculations, we theoretically study the interaction of water, hydroxyl groups, as well as hydrogen and oxygen atoms with MTBs of various types in MoSe 2 monolayer, a typical TMD.…”

Matrix effects on the performance and mechanism of Hg removal from groundwater by MoS2 nanosheets

“…37 Despite of superb Hg removal performance by MoS2, previous studies mainly focused on the Hg removal in deionized (DI) water or buffered solutions. 32,[37][38][39] Considering limited pretreatment approaches for rural communities to moderate the impacts of the groundwater constituents, we believe it is of great importance to study the matrix effects on the Hg removal from groundwater, and to unravel the applicability of MoS2 in the remediation of Hg-contaminated groundwater.…”
