A comprehensive review on bismuth-sulfide-based compounds

Synergistic effect of a bamboo-like Bi2S3 covered Sm2O3 nanocomposite (Bi2S3–Sm2O3) for enhanced alkaline OER

“…27 Among these, bismuth sulphide Bi 2 S 3 has emerged as a versatile electrocatalyst for electrocatalytic water splitting. 28 Bi 2 S 3 is an earth-abundant transition metal sulfide and an n-type semiconductor that belongs to the V and IV groups. 29 Bi 2 S 3 has inherent high electrical conductivity, enriched surface active sites, enhanced reactivity, low intrinsic electrical resistance, and a high surface-to-volume ratio.…”

“…30,31 Bi 2 S 3 has a lamellar structure, where Bi and S atoms are interlinked with each other by strong covalent bonds in a plane, while outside the plane they are interlinked by weak bonds along the preferred growth orientation. 32,33 This unique design of Bi 2 S 3 coupled with Sm 2 O 3 offers a channel for charge transport that favors the OER activity. In this unique structure, bismuth plays the role of a mediator to shuttle the charges between Bi 2 S 3 and Sm 2 O 3 and promotes the separation and transfer of charge carriers at the electrode surface.…”

Deciphering the mechanistic insights of 4-nitrophenol reduction catalyzed by a 1D–2D Bi2S3 nanostructured catalyst

“…20 Among them, bismuth-containing chalcogenides have been investigated for many catalytic applications for various reasons, including their abundance, relatively non-toxic nature, affordability in production, stability, large surface area, and flexibility in size and shape, including 1D, 2D, and 3D morphologies. 21–24 Initially, the semi-metallic Bi nanoparticles were deemed a promising contender for catalyzing the reduction of 4-NP, but their easy aggregation significantly diminished their catalytic activity. 25 Hence, the rational design and synthesis of bismuth-based nanostructured catalysts other than Bi nanoparticles (NPs) with controlled morphologies are crucial for developing catalysts at reduced cost with improved catalytic performance.…”

Low-Temperature Synthesis of Bi2S3 Hierarchical Microstructures via Co-Precipitation and Digestive Process in Aqueous Medium

“…These atoms arrange themselves in slats along the c-axis and are stacked together by intermolecular bonds along the a-axis, resulting in the formation of three-dimensional lamella-like structures [12]. These structural properties allow Bi 2 S 3 to develop crystalline habits such as nanorods, nanosheets, and acicular structures [13][14][15][16][17][18][19][20][21].…”
