Synthesis of SnS ₂ nanoparticles by a surfactant-mediated hydrothermal method and their characterization

Abstract

SnS 2 nanoparticles have been synthesized using a mild hydrothermal method in the presence of the surfactant sodium dodecyl sulfate (SDS) at 180 • C for 12 h. Physical investigations were carried out to study their structure, size, morphology and optical properties. The x-ray diffraction (XRD) pattern of the as-prepared sample is indexed to the hexagonal phase of SnS 2 and the particle size is 100 nm, which is further confirmed by transmission electron microscopy (TEM). The UV-visible spectrum shows that the absorption edge is blue shifted, and the band gap of the prepared SnS 2 nanoparticles has been evaluated with UV-visible spectroscopy to be 3.54 eV, which is larger than the bulk SnS 2 (∼2.44 eV). The anionic surfactant SDS plays a key role in the formation of the 3D sphere like SnS 2 nanostructures. A probable reaction for the formation of nanocrystalline SnS 2 nanoparticles is proposed.

Unlocking the potential of SnS2: Transition metal catalyzed utilization of reversible conversion and alloying reactions

“…SnS 2 nanosheets (~1.2 mg cm −2 ) were uniformly grown onto 3DG through a facile solvothermal synthesis process where surfactant (SDS), was used to reduce the size of the nanosheet (Fig. 1c)3132. This creates a denser loading of SnS 2 on 3DG (Figure S1, see Supporting Information).…”

Surfactant-aided sol-gel synthesis of TiO2–MgO nanocomposite and their photocatalytic azo dye degradation activity

“…At higher loads of magnesium particle, the nanocomposite can block some active sites and reduce the effectiveness of the active phases. 24,26 Thus, an optimal combination of magnesium and surfactant Ti-M-S1 (1%) would be most effective in optimizing the removal efficiencies of MB and MO dyes.

“…Complete gelation was then achieved by placing the sol-containing solution in an oven at 80℃ for 12 h. Subsequently, the wet gel was dried overnight at 100℃ under atmospheric pressure to obtain the zero gel. The dried zero gel material was calcined at 500℃ for 3 h to remove the surfactant, 24 consequently producing the desired Ti-M-S1 and Ti-M-S2 mixed-metal nanocomposites for SDS and Triton X-100 surfactant-aided synthesis, respectively.…”

“…Precipitation in the presence of surfactant molecules is an efficient approach for one-step homogeneous surface modification of the particles and for controlling the size and the surface chemistry. 24,25. The literature abounds with reports on the synthesis of metal oxide nanoparticles, such as nickel and silver oxide, in either organic or aqueous solutions using various commercially available surfactants, such as sodium dodecyl sulfate (SDS), tri-noctylphosphine, triton X-100, cetyltrimethylammonium bromide, cetyltrimethylammonium chloride, and cetylpyridinium chloride.…”

N-Tipi SnS2 Yarıiletken İnce Filmlerin Hazırlanması ve Karakterizasyonu

“…SnS2 yarıiletken ince filmleri birçok yöntemle elde edilebilmektedir bu yöntemler arasında hidrotermal [14], ardışık iyonik tabaka adsorpsiyon ve reaksiyon yöntemi (SILAR) [15], plazma destekli kimyasal buhar biriktirme (PECVD) [16], spray pyrolysis tekniği [17], fiziksel buhar biriktirme yöntemi [18], sol-jel tekniği [19] ve kimyasal depolama yöntemi [20] sayılabilir. Kimyasal depolama yöntemi bu yöntemler arasında en basit ve ekonomik olması nedeniyle diğer yöntemlere göre daha avantajlıdır.…”
