Bi2S3 nanostructures: A new photocatalyst

Abstract

Uniform colloidal Bi 2 S 3 nanodots and nanorods with different sizes have been prepared in a controllable manner via a hot injection method. X-ray diffraction (XRD) results show that the resulting nanocrystals have an orthorhombic structure. Both the diameter and length of the nanorods increase with increasing concentration of the precursors. All of the prepared Bi 2 S 3 nanostructures show high efficiency in the photodegradation of rhodamine B, especially in the case of small sized nanodots-which is possibly due to their high surface area. The dynamics of the photocatalysis is also discussed.

Bismuth Sulfide (Bi2S3) Nanorods as Efficient Photodetection Materials

“…In recent years, nanosized Bi 2 S 3 of various morphologies and sizes has been used as promising materials in photovoltaics (solar cell) [2], photodetection [3][4][5], photocatalysis [6], photothermal conversion [7], thermoelectrics [8], and so on. In particular, much attention is being paid on one-dimensional (1D) rod-like Bi 2 S 3 nanomaterials and their optical and photoelectronic performance.…”

Development of Bismuth Sulphide Quantum Dot

“…Lately, Bi 2 S 3 nanostructures with different morphologies including nanotubes, nanorods or nanowires, nanoribbons, and nanocomposites have been prepared through various techniques. Single precious stone orthorhombic Bi 2 S 3 nanostructures with different morphologies, including wires, poles, and blossoms have been controllably synthesized [6].Bismuth sulfide (Bi 2 S 3 ) is a piece of a group of mixes (Pn 2 X 3 where Pn = Sb, Bi and X = S, Se, Te), which are thought to be most encouraging for thermoelectric applications, as exhibited by the exponential development of productions in regards to this material beginning from 1990 [7]. X-ray processed tomography applications of Bi 2 S 3 nanoparticles are described by Rabin et al Bi 2 S 3 nanoparticles are better than the iodinated particles, which are utilized these days have high X-ray absorption and course times i.e.…”

Novel one-pot synthesis and sensitisation of new BiOCl–Bi2S3 nanostructures from DES medium displaying high photocatalytic activity

“…This approach shows advantages over other methodologies reported in the past in which high reaction temperature, capping agents and use of less environmentally friendly reactants were required. [29][30][31][32] The presence of Bi2S3, which has a band gap energy in the range 1.2 to 1.8 eV 26,[33][34][35] , extends the absorption of the hybrid material to the visible region since BiOCl only absorbs in the UV (Eg BiOCl bulk = 3.5 eV). The BiOCl/Bi2S3 nanomaterials exhibit efficient visible light photocatalytic activity towards RhB, 2,4-dichlorophenol and MO degradation processes.…”
