Solvothermal synthesis of Bi24O31ClxBr10−x solid solutions with enhanced visible light photocatalytic property

Influence of the Facets of Bi24O31Br10 Nanobelts and Nanosheets on Their Photocatalytic Properties

“…The spacing between adjacent lattice planes of 0.28 nm was ascribed to the (117) facet [22]. The interfacial angle between the (117) and (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) planes was estimated to be 89°, as shown by the selected area electron diffraction patterns (SAED, Figure 2d), and is consistent with the theoretical value. Therefore, the (117) facet was identified as the main exposed facet of the BOB-NS.…”

“…Therefore, tremendous research efforts have been devoted to improving its photocatalytic activity. Some studies have demonstrated that the photocatalytic activity of Bi 24 O 31 Br 10 can be further enhanced by doping it with other elements, for example Bi 24 O 31 Cl x Br 10−x and Er-doped Bi 24 O Br 10 [10,11]. This could also be achieved by controlling the three-dimensional (3D) morphology and thickness of Bi 24 O 31 Br 10 NSs [12][13][14] [15][16][17], and the synthesis of Bi 24 O 31 Br 10 with oxygen and bromine vacancies or the formation of Bi 24 O 31 Br 10 (OH) [18][19][20].…”

A review on bismuth oxyhalide based materials for photocatalysis

“… 169,170 However, due to the non-uniform synthesis conditions, little work has been performed on bismuth-rich Bi x O y X z solid solutions. In 2015, Liu et al reported the synthesis of Bi 24 O 31 Cl x Br 10− x solid solutions using a solvothermal method for the first time, 171 where the Bi 4 O 5 BrI solid solution with the optimal ratio ( x = 1) displayed the highest photocatalytic activity for the photocatalytic reduction of CO 2 and Cr( vi ) under visible light irradiation ( Fig. 17 ).…”

pH-regulated hydrothermal synthesis and characterization of Sb4O5X2 (X = Br/Cl) and its use for the dye degradation of methyl orange both with and without light illumination

“…13 Recently, oxyhalide and metal oxyhalide compounds have been shown as potential photocatalysts, e.g., Bi 2 MO 4 Cl (M ¼ Y/La/Bi), PbBiO 2 X, Bi 12 O 17 Cl 2 , Bi 3 O 4 Cl, Bi 24 O 31 Cl x Br 10Àx , PbBiO 2 Br/BiOBr, PbBiO 2 Br/UiO-66-NH 2 (mpg-C 3 N 4 /PbBiO 2 Br), Bi 4 NbO 8 Cl, Bi 24 O 31 Cl 10 . 1,2,5,[14][15][16] Visible light responsive photocatalysis is responsible for the photocatalyzed decolorization of a dye in solution via a photoexcitation process. 17 Despite substantial research endeavours in the eld of visible light responsive photocatalysts during past few decades, development of such materials still remains a challenge for us.…”
