Highly efficient visible-light photoactivity of Z-scheme MoS2/Ag2CO3 photocatalysts for organic pollutants degradation and bacterial inactivation

Tuning the photocatalytic/electrocatalytic properties of MoS2/MoSe2 heterostructures by varying the weight ratios for enhanced wastewater treatment and hydrogen production

“…But compared with the pure MoS 2 and MoSe 2 the peaks in the composite are slightly shied and this type of trend implies close contact and higher interaction between MoS 2 and MoSe 2 in the composites. 34 3.1.6 Surface area studies. To analyze the surface area of the as-prepared nanocomposites, specic surface area analysis was carried out.…”

Solar‐Driven Photocatalytic Disinfection Over 2D Semiconductors: The Generation and Effects of Reactive Oxygen Species

“…The MoS 2 /Ag 2 CO 3 heterojunction thereby disinfected 7 log E. coli within 80 min in the presence of visible light. [ 102 ] Some MoS 2 tends to distribute in the form of clusters and displays a flower‐like morphology. The flower‐like nanospheres with more exposed active sites offer a framework for nanoparticles deposition, as can be found in the MoS 2 /Ag/AgS 2 and MoS 2 /Bi 2 MoO 6 photocatalysts (Figure 5e).…”

Photocatalytic Evaluation of Ag2CO3 for Ethylparaben Degradation in Different Water Matrices

“…Moreover, the as prepared Ag 2 CO 3 photocatalyst has similar activity with heterostructures that include it. Specifically, Ag 2 CO 3 /ZnO led to complete rhodamine B degradation after 120 min of visible light irradiation [19], while Ag 2 CO 3 /MoS 2 composite photocatalysts degraded Lanasol Red 5B in 25 min [18]. However, these works study photocatalytic degradation of dyes and not micropollutants, in which the results are often overrated due to photo-sensitization of the catalyst.…”

“…Its satisfying photocatalytic performance is derived from the fact that the bottom of the conduction band (CB) in Ag 2 CO 3 consists mainly of hybridized Ag s-Ag s states responsible for its high dispersity, which allows high photogenerated electrons mobility and prevents photogenerated charge carrier's recombination [15]. In order to increase its photocatalytic properties, a wide range of heterojunctions have also been synthesized, such as Ag 2 CO 3 /TiO 2 [16], ZnO/Ag 2 CO 3 /Ag 2 O [17], MoS 2 /Ag 2 CO 3 [18], and ZnO/Ag 2 CO 3 [19].…”
