Construction of novel BiOCl/MoS2 nanocomposites with Z-scheme structure for enhanced photocatalytic activity

Structure regulation and photocatalytic activity enhancement of Bi2WO6by “double‐effect modification” mode

“…The presence of Bi, O, W, and Cl elements can be seen from the total map of Figure A. Figure B shows the Bi 4f spectrum of the prepared sample with two peaks detected at about 159.2 and 164.5 eV, which represented Bi 4f 7/2 and the accompanying peak Bi 4f 5/2 , corresponded to Bi 3+ ; Figure c shows the O 1s spectrum of O 2‐ in the sample, the binding energy was detected at 530.5 eV; in Figure D, two peaks detected at 35.2 and 37.5 eV, respectively, corresponding to the binding energy of W 4f 7/2 and the accompanying peak W 4f 5/2 , which corresponds to W 6+ ; Figure e shows the Cl 2p spectrum of the sample, two peaks of Cl ‐ were detected at 197.7 and 199.2 eV, respectively, which correspond to the binding energy positions of Cl 2p 3/2 and the accompanying peak Cl 2p 1/2 . The results of XRD, EDS, and XPS analysis consistently show that Cl ‐ was successfully introduced into Bi 2 WO 6 lattice by solvothermal reaction.…”

The construction of a photocatalytic fuel cell based on piezoelectric-enhanced dual heterojunctions of PVDF–HFP supported 2D/3D composites toward photocatalytic degradation of tetracycline

“…8a, ZnO, BiOBr and g-C 3 N 4 have obvious absorption intensity at about 400 nm, 32,51 while MoS 2 has a prominent absorption edge at 300–600 nm. 52 For all materials, UV spectra ( λ < 420 nm) show significant absorption, and visible light ( λ ≥ 420 nm) is quite different. It can be seen that the photocatalytic effect can occur in the full spectrum light source, and the piezoelectric photocatalytic performance can be improved.…”

Enhancing the MoS2/MoO3/ZnS/Zn-Heterojunction catalyst's photocatalytic performance for water organic pollutants

“…(Abundant) Graphene like molybdenum disulfide (MoS 2 )-based photocatalysts have been studied in many fields, like photocatalysis, solar cells, biomedical, sensors, and environmental remediation because of their excellent chemical stability, suitable, excellent optical absorption property, fast charge carrier dynamics [14], non-toxic and even redox capacity of perfected electron-hole pairs [15,16]. In spite of most of the physical properties of MoS 2 being similar to graphene, it has achieved superior advantages due to its low cost and good light absorption capacity [17] .…”
