Highly efficient visible-light photocatalytic activity of MoS₂–TiO₂ mixtures hybrid photocatalyst and functional properties

Abstract

2D-layered molybdenum disulfide (MoS2) and MoS2/TiO2 nanocomposite were synthesized by a hydrothermal method.

2D/2D Heterojunction of R-scheme Ti3C2 MXene/MoS2 Nanosheets for Enhanced Photocatalytic Performance

“…The relatively narrow bandgap (Eg = 1.8 eV), unique optical properties and layered structure of MoS 2 nanosheets have attracted more and more attention [15][16][17][18]. MoS 2 has been coupled with several two-dimensional (2D) materials and semiconductors, such as TiO 2 [19], graphene oxide (GO) [20], g-C 3 N 4 [21], SnO 2 [12], Bi 2 WO 6 [22], Bi 2 O 2 CO 3 [23], and CdS [24], in order to improve the efficiency of photocatalytic degradation and hydrogen production. It has been proved that higher concentration of methyl orange (MO) (30 mg/L) organic pollutants can be degraded in 60 min under the visible light irradiation by MoS 2 /CdS nanocomposites [24].…”

Ultrathin layered MoS2 nanosheets with rich active sites for enhanced visible light photocatalytic activity

“…These properties make MoS 2 a functional material with a wide range of applications, such as the counter electrode in solar cell, hydrogen evolution reactions, 2-5 lubricants, 6 and as a photocatalyst. The earth abundant, 7 highly active edge sites, [8][9][10][11][12] large exciton binding energy, 13 high anisotropic, 14,15 and visible active region [16][17][18] are some of the major advantageous of MoS 2 . MoS 2 has two exposed surfaces, namely, the basal plane (002) and the edge sites plane (100), due to its high anisotropy crystal nature.…”

Carbon Dioxide Photoreduction on the Bi2S3/MoS2 Catalyst

“…Chalcogen compounds, such as CdS [6], ZnS [7], SnS 2 [8], NiS [9], Bi 2 S 3 [10], CuS [11], and MoS 2 [12], can be used for water decomposition or CO 2 conversion, and these have produced quite reliable results. Specifically, CdS has been evaluated as one of the most promising catalyst candidates for water decomposition under visible light, which is thermodynamically advantageous, as the positions of the valence and conduction bands overlap with the oxidation and reduction potentials of water [13,14].…”
