Microwave-assisted hydrothermal synthesis of BiOCl/Bi2WO6 nanocomposites for the enhancement of photocatalytic efficiency

Preparation of BiOCl/Bi2WO6 Photocatalyst for Efficient Fixation on Cotton Fabric: Applications in UV Shielding and Self-Cleaning Performances

“…The peaks at 159.5 eV and 164.7 eV in Figure 4b corresponded to Bi 4f 7/2 and Bi 4f 5/2 , respectively, which confirmed the presence of Bi 3+ ions [36]. The peaks at 530.0 eV and 531.8 eV in Figure 4c could be ascribed to the lattice oxygen of the BiOCl/Bi 2 WO 6 composite and the hydroxyl groups of the absorbed H 2 O molecules, respectively [37]. The Cl 2p spectrum in Figure 4d was fitted by two peaks with the binding energy at 199.8 eV and 198.2 eV, corresponding to Cl 2p 1/2 and Cl 2p 3/2 peaks, respectively [38].…”

Construction of a flower-like S-scheme Bi2WO6/BiOCl nano-heterojunction with enhanced visible-light photocatalytic properties

“…It can be observed in Fig. 1(b) that for the Bi 2 WO 6 /BiOCl-3 composite, the XRD diffraction peaks at 2 θ = 28.42° and 32.83° marked by a triangle correspond to the (131) and (002) crystalline planes of Bi 2 WO 6 , 32,33 and the diffraction peaks with 2 θ values of 11.97°, 24.30°, 26.17°, 33.55°, and 36.65° indicated by asterisks are indexed to (001), (002), (101), (102), and (003) crystalline planes of BiOCl. 34 Such an XRD pattern represents the coexistence of both Bi 2 WO 6 and BiOCl phases.…”

Selective Photocatalytic Reduction of CO2 to CH4 Modulated by Chloride Modification on Bi2WO6 Nanosheets

“…XPS measurements were carried out to elucidate the surface composition and chemical states. In the high-resolution Cl 2p spectra (Figure a), two distinct peaks at 199.4 and 197.8 eV, which are attributed to Cl 2p 1/2 and Cl 2p 3/2 , respectively, are observed for BW-Cl3 and BW-Cl5 . According to other similar chloride-modified materials, chlorides are considered to be successfully bonded with bismuth ions in our synthesized ones.…”
