Insights into the photosensitivity activity of BiOCl under visible light irradiation

Photocatalytic properties of hierarchical BiOXs obtained via an ethanol-assisted solvothermal process

“…The band gaps of the samples could be deduced from plots ( Fig. 4b) of (αhν) 1/2 versus energy (hν), and were calculated to be 3.24, 2.70 and 1.79 eV for BiOCl, BiOBr and BiOI, respectively, which are consistent with those reported previously (Liu et al, 2014;Su et al, 2014;Hu et al, 2014). According to Fig.…”

Hierarchical BiOCl microflowers with improved visible-light-driven photocatalytic activity by Fe(III) modification

“…The method for preparing the working electrode was described in detail in our previous works [9]. The electrolyte was 0.2 M Na 2 SO 4 solution.…”

“…Bismuth oxychloride (BiOCl) is one of the promising photocatalysts, featured with the tetragonal layered structures of [Bi 2 O 2 ] slabs interleaved with double Cl slabs, endowed with an efficient separation of photoinduced charges [3,4]. Thus, considerable efforts have been devoted to prepare BiOCl nanostructures with a diversity of well-defined morphologies, such as nanosheets [4][5][6], nanoplates [7][8][9], and nanodisks [10], and nanoflakes [11]. Moreover, these nanostructures can act as the building blocks to self-assemble into three dimensional (3D) hierarchical structures with superior photocatalytic performance.…”

Photocatalytic degradation and electricity generation in a rotating disk photoelectrochemical cell over hierarchical structured BiOBr film

“…The effective electron injection and the subsequent formation of O 2 • − require the good energy matching and enough redox potential of the conduction band of semiconductor [40]. For n-type semiconductor, the conduction band potential is very close to the flat-band potential (V fb ) and we have calculated the V fb of BiOBr and BiOCl films through the Mott-Schottky plots.…”
