Morphological variations in Bi2S3 nanoparticles synthesized by using a single source precursor

Abstract

A simple solvothermal decomposition of bismuth dithiocarbamate complex in oleylamine, oleic acid, and hexadecylamine at 180 °C, yielded bismuth sulphide nanomaterials of different morphologies represented as Bi 2 S 3 (OAm), Bi 2 S 3 (OAc) and Bi 2 S 3 (HDA) respectively. The bismuth complex, used as the single source precursor, was synthesized and characterised by elemental analysis, FTIR, and NMR spectroscopic techniques. The spectroscopic and micro analysis confirmed the proposed compound, while the as-prepared nanoparticles were characterized using UV-visible spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive spectrometer (EDS). The effects of the different solvent media on the structural properties of the obtained Bi 2 S 3 were investigated. An orthorhombic phase bismuthinite of varying intensities were obtained, with an indication that a bias of orientations existed in the (2 1 1) crystallographic planes in the Bi 2 S 3 (OAm) compared to the characteristic (1 3 0) diffraction peak of Bi 2 S 3 . The microscopic analysis showed a correlation between the nanoparticles' morphology and the type of solvent used, which also implied that the properties of Bi 2 S 3 were affected by the solvent medium.

“…2e and f ) NRs implied that the weight percentages of Bi and S decreased from 78.2% and 21.8% to 77.0% and 17.7%, respectively, after HA coating. 64 We also found that O (1.1%) and N (0.1%) elements were present in BiH NRs, indicating the successful introduction of HA to the surface of Bi 2 S 3 NRs. In addition, UV-Vis spectra of both Bi 2 S 3 and BiH NRs showed an obvious absorption at 808 nm, indicating their potential to be photothermal agents (Fig.…”

Study of the Potential of La/Bi2S3 Catalyst for Photodegradation of Acid Yellow 42 Dye under Visible Light

“…However, adding La increased the intensity of the (211) plane of Bi 2 S 3 at the diffraction peak 2 = 28:65 °. It indicated the bias of orientations of these crystallographic planes [29]. The 211 facets were the most dominant in Bi 2 S 3, suggesting the formation of microsphere 5 Journal of Nanomaterials particles [30].…”
