Visible Light‐Driven BiOBr/Bi2S3@CeMOF Heterostructured Hybrid with Extremely Efficient Photocatalytic Reduction Performance of Nitrophenols: Modeling and Optimization

“…In addition to the appearance of two peaks at 885.4 and 904.1 eV, it demonstrates Ce 3+ 3d state [37] . The peaks at 160.6, 161.6, 162.5, 163.3 eV can be considered to Bi 4 f 7/2, Bi 4 f 5/2, respectively [38] . The peaks at 66.5 and 68.6 eV are signified to the physically adsorbed Br − on the prepared material, while the band at 69.6 and 71.1 eV are denoted to Br 3d 5/2, and Br 3d 3/2 of the BiOBr/Bi 2 S 3 composite, [39] respectively.…”

[38] The peaks at 66.5 and 68.6 eV are signified to the physically adsorbed Br À on the prepared material, while the band at 69.6 and 71.1 eV are denoted to Br 3d 5/2, and Br 3d 3/2 of the BiOBr/Bi 2 S 3 composite, [39] respectively. The XPS of O 1s is divided into three peaks at 531.9, 533.0, 535.9 eV fitted to the BiÀ O (lattice oxygen), oxygen, water, and carbonate adsorbed on the surface.…”

Photocatalytic oxidation of pollutants in gas-phase via Ag3PO4-based semiconductor photocatalysts: Recent progress, new trends, and future perspectives

“…(Fig. 1) (i) Aqueous phase organic pollutants degradation (Deng et al, 2020;Fiorenza et al, 2020;Naciri et al, 2020aNaciri et al, , 2019bNaciri et al, , 2019a and (ii) Gaseous phase pollutants removal (Aramendía et al, 2007;Araña et al, 2004;Liao et al, 2017;Reyna-Cavazos et al, 2020). This technology is considered the newest generation of air cleaning technology.…”

Photocatalytic Reduction of Hexavalent Chromium (Cr6+) Over BiOI Calcined at Different Temperature Under Visible Light Irradiation

“…[9] Apart from visible light utilization, bismuth oxyiodide (BiOI) is hampered by high charge carrier recombination of which reduce its photocatalytic activity count. Different researchers have studied on the modification of BiOI to counteract the challenge of charge carrier recombination and band gap engineering including structural modification, [10][11][12][13][14][15] doping, [16][17][18] modification with carbonaceous materials, [19][20][21][22][23] plasmonic material [24] and heterojunction composite formation. [25][26][27][28][29][30][31] Herein, this study investigated the effect of calcination temperature on the phase transformation and photocatalytic reduction of hexavalent chromium performance of bismuth…”
