“…[ 64 ] Padervand reported sheet‐like BiOCl/AgCl‐BiOI/AgI quaternary nanocomposites using a simple single‐step co‐precipitation method that exhibited high resistance to Gram‐negative ( E. coli ) and Gram‐positive ( S. aureus ) pathogenic bacteria concentrations after 5 h under light illumination. [ 65 ] Li et al. fabricated a novel β‐Bi 2 O 3 @BiOBr core/shell photocatalyst and thus enabled the efficient separation of photogenerated electron–hole pairs, which can completely deactivate S. aureus and E. coli under 50 min of LED light irradiation ( Figure ).…”

Studies of layered structure nanomaterials is greatly explored to provide enormous potential for the development of photocatalytic bioapplication. As one of the layered nanomaterials, bismuth halide nanomaterials have attracted much attention due to their outstanding properties, such as excellent optoelectronic performance, higher biosafety, high abundance, etc. Here, a brief review of recent research progress of bismuth halide based nanomaterials (BiONs) in bioapplication is provided, mainly including photocatalytic antibacterial and photodynamic therapy. Surface engineering strategies, including doping, heterojunction, morphology control, vacancy engineering, facet engineering, and others, are employed to develop a high photoactivity and better biological compatibility of BiONs. In this review, the major challenges of BiONs during the photoreaction process are discussed and promising strategies are proposed for superior photocatalytic performance in biological area. It is hoped that this review may offer new insights into the development of highly active nanomaterials in bioapplication.

“…The development of photocatalysts with a broad spectral response is an inevitable tendency for meeting market demands. In order to enhance the visible-light-driven photoactivity of two-component BiOCl-based photocatalysts, a large number of BiOCl-based multiple complex systems have been developed in the past few decades. − Thereby, the introduction of materials with a narrow band gap and rapid electron transfer as well as improved light absorption in multiple complex BiOCl-based systems is conducive to boost the fast separation of electron–hole pairs and enhance visible light absorption of BiOCl, leading to an improved photocatalytic activity compared with the two-component BiOCl-based photocatalysts and pristine BiOCl. − …”

“…In order to obtain ultrahigh separation and migration efficiency of carriers and broader light absorption region, some quaternary BiOCl-based photocatalysts have been synthesized recently. ,− For example, magnetic g-C 3 N 4 /Cu 2 O/Fe 3 O 4 /BiOCl heterojunctions with flower-like BiOCl, cubical Cu 2 O and spherical Fe 3 O 4 NPs attached on the surface of sheet-like g-C 3 N 4 can be synthesized by a coprecipitation strategy . In this system, coupling BiOCl/g-C 3 N 4 /Cu 2 O (p-n-p heterojunction) with Fe 3 O 4 NPs can bring out enhanced photoactivity, a suitable band gap, a broader light absorption region, and higher separation and migration efficiency of charge carriers due to the role of internal electrical fields.…”

The construction and regulation of heterogeneous interfaces are beneficial to improve solar light harvesting and photocharge separation of hybrid BiOCl-based photocatalysts, which are attributed to the synergistic effects that originate from the integrated interaction between disparate components. With the rapid development of synthetic technologies, hybrid BiOCl-based micro-/nanostructures with diversified components, morphologies, and sizes have been well prepared. Moreover, hybrid BiOCl-based photocatalysts have presented a promising potential for various photocatalytic applications, such as organic pollutant degradation, hydrogen production, NO removal, CO2 reduction, heavy metal ion detection, disinfection, nitrogen fixation, and alcohol oxidation. Previously, several review articles have mainly summarized the advances made in synthetic methods, morphological control, modification strategies, and applications of the bare BiOCl micro-/nanostructures. However, a comprehensive overview based on the type of species and the corresponding correlations between microstructures, performances, as well as photocatalytic mechanisms has been less reported for hybrid BiOCl-based photocatalysts so far. Therefore, a comprehensive understanding of the basic theory and research progress of hybrid BiOCl-based photocatalysts is imperative. This review aims to provide an overview of the important advances made in eight types of hybrid BiOCl-based photocatalysts, including metal/BiOCl, metal oxide/BiOCl, metal sulfide/BiOCl, BiOX (X = Cl, Br, I)/BiOCl, AgX (X = Cl, Br, I)/BiOCl, organics/BiOCl, carbon/BiOCl, and other BiOCl-based multicomponents. In each classification, the synthetic methods, modification strategies, relationships between interfacial microstructures, and enhanced performances are discussed based on some typical examples. Additionally, some scientific issues and potential directions are also given. Hopefully, this review paper will provide a useful reference for researchers currently focusing on exploring new BiOCl-based photocatalysts.

“…[16][17][18] Therefore, BiOI has recently attracted broader concerns in the eld of water purication under visible light conditions. [19][20][21] Despite its many advantages, the practical application of BiOI is still limited due to its low efficiency of utilizing visible light. 18,[22][23][24] This is because the hybridization of the valence band Bi 6s and O 2p orbitals makes the carriers easy to recombine.…”
