A solvothermal method has been employed to synthesize bismuth sulfide (Bi2S3) with three-dimensional (3D) hierarchical architectures. The influences of different types of surfactants and Cl(-) species on the size and morphology were investigated. A possible formation mechanism was also proposed on the basis of time-dependent experiments. The photoresponse properties show that the conductivity o...

Hierarchical, core-shell structured microspheres of bismuth chalcogenides (Bi2E3, E ) S, Se, Te) have been synthesized by chemical transformation of reactive precursor templates, which involves the formation of intermediate BiOCl mircrospheres and their subsequent hydrothermal transformation into Bi2E3 core-shell microspheres. The uniform precursor microspheres consisting of BiOCl nanoplates we...

To develop Bi2S3-based heterojunction for efficient solar light induced photoreduction of Cr(VI), flower-like Bi2S3–In2S3 composites consisted nanorods were prepared via a microwave-assisted hydrothermal route. In contrast with pure Bi2S3, exhibited the enhanced activity while decreased adsorption capacity Cr(VI) removal. The best removal efficiency 70 mg L?1 solution (99.86%) was achieved by o...

The new catalyst (La/Bi2S3) applies for the photodegradation of Acid Yellow 42 (AY42) dye under visible light in this study. La/Bi2S3 material is motivating due to excellent ability Lanthanum (La) increase adsorption capacity and electron-hole separation Bi2S3 enhancing degradation AY42. characterization analysis prepared confirms a successful synthesis using hydrothermal method. efficiency AY4...

Bi2S3 nanostructures with a sheaflike morphology are obtained via reaction of bismuth acetate-oleic acid complex with elemental sulfur in 1-octadecence. These structures may form by the splitting crystal growth mechanism, which is known to account for the morphology some mineral crystals assume in nature. By control of the synthetic parameters, different shapes are obtained, analogous to those ...

Bismuth sulphide (Bi2S3), an n-type semiconductor that critically demonstrates the Seebeck effect with coefficients of about 300 μVK−1. However, its poor electrical conductivity makes it unsuitable for thermoelectric applications. In this study, we present a facile preparation method fabricating Bi-sprayed Bi2S3 particles alters their properties. Samples were created differing Bi concentrations...

Porous Bi2O3–Bi2S3 composite sheets were constructed through a combinational methodology of chemical bath deposition and hydrothermal reaction. The Na2S precursor concentration in the solution was varied to understand correlation between vulcanization degree structure evolution porous sheets. control etching rate Bi2O3 sheet template regrowth Bi2S3 crystallites via suitable sulfide during react...

BACKGROUND X-ray computed tomography (CT) imaging can be used to reveal the three-dimensional structure of deep tissue with high spatial resolution. However, it cannot reveal molecular or cellular changes, and has great limitations in terms of specificity and sensitivity. Fluorescence imaging technology is one of the main methods used for the study of molecular events in vivo and has important ...

The engineering of an efficient electrochemical sensor based on a bismuth sulfide/reduced graphene oxide (Bi2S3/rGO) composite to detect ascorbic acid (AA) is reported. Bi2S3 nanorods/rGO was synthesized using facile hydrothermal method. By varying the amount (GO) added synthesis, morphology and size nanorods anchored surface rGO can be tuned. Compared bare glassy carbon electrode (GCE), GCE mo...

Along with continuous growing widespread adulterations of botanical drugs, the necessity for drug quality monitoring has become more popular than ever. Considering that antioxidants are widely found in natural plant pharmaceuticals, gallic acid (GA) is often regarded as the reference standard to make sure whether these are up to grade as guided by Chinese Pharmacopeia. Herein, a novel Bi2MoO6/B...
