“…After 180 minutes of visible light irradiation, the degradation rate of resorcinol reached 93.8% and still maintained excellent stability after four cycles. Meanwhile, through one-step hydrolysis, Mi et al 52 synthesized belt-like Bi 4 O 5 Br 2 using bismuth subsalicylate (BiSSA) ribbons as bismuth sources for degradation of salicylic acid (SA) and resorcinol (RO). During the synthesis process, Br − can directly replace OH − without destroying its morphological structure.…”

“…In addition to H 2 generation, the increased CB also promoted photocatalytic molecular oxygen activation in Bi 24 O 31 Cl 10 . Further, the Bi-rich Bi x O y X z possesses enhanced light-harvesting ability that is attributed to the modulated band structure, thus breaking the bottleneck of limited photoabsorption caused from the wide bandgap energy of BiOCl and BiOBr [68]. The higher photon absorption efficiency of Bi x O y X z in comparison to BiOX induces greater electric field intensity, which in turn leads to large dipole moment.…”

Semiconductor-based photocatalysis has been identified as an encouraging approach for solving the two main challenging problems, viz., remedying our polluted environment and the generation of sustainable chemical energy. Stoichiometric and non-stoichiometric bismuth oxyhalides (BiOX and BixOyXz where X = Cl, Br, and I) are a relatively new class of semiconductors that have attracted considerable interest for photocatalysis applications due to attributes, viz., high stability, suitable band structure, modifiable energy bandgap and two-dimensional layered structure capable of generating an internal electric field. Recently, the construction of heterojunction photocatalysts, especially 2D/2D systems, has convincingly drawn momentous attention practicably owing to the productive influence of having two dissimilar layered semiconductors in face-to-face contact with each other. This review has systematically summarized the recent progress on the 2D/2D heterojunction constructed between BiOX/BixOyXz with graphitic carbon nitride (g-C3N4). The band structure of individual components, various fabrication methods, different strategies developed for improving the photocatalytic performance and their applications in the degradation of various organic contaminants, hydrogen (H2) evolution, carbon dioxide (CO2) reduction, nitrogen (N2) fixation and the organic synthesis of clean chemicals are summarized. The perspectives and plausible opportunities for developing high performance BiOX/BixOyXz-g-C3N4 heterojunction photocatalysts are also discussed.

“…They show magnificent response towards light either by direct utilization of excited electron in rare earth metal ion or by indirect utilization of the emitted short-wavelength light which is absorbed by semiconductors [195][196][197][198]. Lastly, Bi doping [199], even bismuth-rich technique is another advisable way to augment the photocatalytic reduction activity of Bix-OyXz (X = Cl, Br, I) [200]. Theoretical calculations have shown that the CB of bismuth-based compounds mainly consists of Bi 6p orbits [163].…”

Bismuth-based binary compounds, including Bi2Se3 and Bi2Te3, have attracted increasing attention as well-known topological insulators. On the other hand, bismuth-based ternary compounds exhibit diverse properties, such as, ultrahigh carrier mobility, and strong Rashba spin splitting. Moreover, they boast of superior photocatalytic properties, implying great potential to be used in a wide range of applications. The unique structure and properties of two-dimensional (2D) materials, especially the extraordinary electronic and optical properties of 2D Bi2O2Se, have given rise to significant research interests for the exploration of 2D bismuth-based ternary compounds. In this review, we will comprehensively discuss the properties of three important families of bismuth-based ternary compounds, including Bi2O2X (X = S, Se, Te), BiTeX (X = Cl, Br, I), and BiOX (X = Cl, Br, I). In particular, we have placed emphasis on the latest progress in their 2D forms, including their novel properties and applications. This review would aid in understanding the superior performance of bismuth-based ternary compounds and offer a perspective for future research on these emerging 2D materials.
