“…35 Yin et al, Hou et al and Xiao et al have reported nanostructured Bi 4 O 5 I 2 successively including nano-akes and nano-roses fabricated via a complicated organic solvent method. [36][37][38] To the best of our knowledge, there has been no report on the synthesis and application of porous Bi 4 O 5 I 2 nanosheets. Herein, we prepared novel mesoporous Bi 4 O 5 I 2 single-crystal nanosheets using a simple one-step method.…”

“…It has been reported that the morphological structure, oxygen vacancy, and hybrid heterostructure regulation could enhance photocatalytic activities. An assembly of hierarchical structures (such as: 1D nanorods/2D nanosheets, 0D/3D flower-like, and core–shell microparticle heterojunctions) can improve light harvesting ability and quicken the separation of photoinduced carriers. − Particularly, biomimetic tremella-like or lantern-like bismuth oxyiodide embedded biochar by an in situ self-template strategy showed superior photocatalytic performance. − Using the synergistic effects of nanostructure and oxygen vacancy, Tian et al improved the visible light performance of BiOCl microspheres to degrade norfloxacin. In addition, Cheng et al prepared Bi 2 S 3 nanocrystals/BiOCl hybrid microspheres which displayed highly efficient photocatalytic activities under visible light .…”

It remains an exciting challenge to achieve a direct production of large quantities of • OH, generated from photogenerated h + using visible-light-driven photocatalysts fabricated by a one-step method. In this work, a series of hierarchical interconnected BiOCl materials with a tunable absorption range for visible light have been successfully prepared through a one-pot molecular self-assembly technology at room temperature. Depending on the modification of polar organic molecules [i.e., thiourea (TU)], the nonpolar layered semiconductor (BiOCl) turned into an efficient visible-light photocatalyst because it possesses a narrower band gap by surface modification introducing oxygen defects. Meanwhile, the tunable three-dimensional hierarchical architecture of BiOCl was fabricated via the self-assembly of two-dimensional nanosheets with the aid of TU, leading to an enhanced specific surface area along with efficient electron−hole pair separation. Moreover, the obtained BiOCl-10 showed a more positive valence band with an optimized hierarchical porous structure, which produced a sufficient amount of • OH directly from the reaction between photogenerated h + and water molecules under visible light. Thereby, the BiOCl-10 materials exhibit high photocatalytic activities for almost completely degrading tetracycline and rhodamine B in 20 min, about 20 times better than that of pure BiOCl. Our work provided an innovation strategy that may deliver a promising way to fabricate BiOCl materials with highly efficient visible photocatalytic activity by direct production of large quantities • OH through its photogenerated h + .

“…The photocatalytic activity of the samples was tested by the reported method [1]. Differently, 20 mg/l MO, 20 mg/l RhB, 15 mg/l MB and 15 mg/l BPA were selected as the simulated pollutants.…”

“…The pollutants contain coloured and colourless materials. Bismuth halide oxide (BiOX, X = Cl, Br, I or F) with an anisotropic layered structure, as a photocatalyst, can decompose the coloured pollutants, especially, such as Rhodamine B (RhB), methyl orange (MO) and methylene blue (MB) [1][2][3][4][5][6][7]. However, there is a paucity of reports about the degradation of the colourless pollutants and the degradation efficiency is relatively low [8][9][10].…”

Bismuth halide oxide with three halogen elements (P-BiOXs) catalyst was prepared by a facile precipitation method at room temperature only for 30 min. Several measurement technologies were employed to characterise the structures and morphologies of the obtained samples. Coloured Rhodamine B (RhB), methyl orange (MO), methylene blue (MB) and colourless bisphenol A (BPA) were selected to evaluate the photocatalytic activity of the samples. The experimental results showed the P-BiOXs thin nanoplates exhibited the most excellent photocatalytic activity among the prepared samples for the degradation of MO under visible light illumination. More importantly, the catalyst P-BiOXs could effectively degradate RhB, MB and BPA. The P-BiOXs catalyst displayed good photocatalytic stability by the recycling tests. The highly efficient visible light catalytic properties of P-BiOXs could be due to the high specific surface area, enhanced light-harvesting ability, the suitable bandgap energy and the lower recombination rate of the photogenerated electrons and holes.
