2022年9月23日 · Lattice-strained Bi 2 S 3 with 3D hierarchical structures are prepared through a top-down route by a topotactic transformation. High-resolution transmission electron microscopy and X-ray diffraction (XRD) confirm the lattice spacing is expanded by prolonged sulfuration.

Bismuth (III) sulfide (Bi2S3) is a chemical compound of bismuth and sulfur. It occurs in nature as the mineral bismuthinite. Bismuth (III) sulfide can be prepared by reacting a bismuth (III) salt with hydrogen sulfide:

2021年2月22日 · We propose the theory of interfacial engineering based on work function and accordingly design the ecofriendly photoresponsive Schottky junction using two kinds of components with different work...

2021年7月16日 · Bismuth sulfide (Bi2S3) nanoparticles (NPs) was effectively synthesized by utilizing bismuth diethyldithiocarbamate (Bi[DTC]3) complex as single-source antecedent. The synthesized Bi2S3 NPs were affirmed by structural, morphological and thermal analysis with various analytical studies.

Bi2S3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Bi–S bond distances ranging from 2.70–3.08 Å.

2021年9月1日 · Orthorhombic Bi 2 S 3 has a strongly anisotropic structure (Pnma space group) consisting of four Bi 2 S 3 units, leading to a 20 atoms unit cell. Each Bi 2 S 3 unit has two nonequivalent Bi sites, which differs in their coordination and three nonequivalent S sites [7].

We have developed a synthesis method for single crystalline Bi 2 S 3 by chemical vapor deposition (CVD). Bi 2 S 3 was grown directly on a SiO 2 substrate using Bi 2 O 3 powder and H 2 S gas instead of conventional sulfur powder. Sulfur powder is broadly used to synthesize 2D materials such as MoS 2, WS 2 and ReS 2 (Table 1).
