Solvothermal growth of Sb2S3 microcrystallites with novel morphologies

Preparation of shuttle‐like Sb2S3 nanorod‐bundles via a solvothermal approach under alkaline condition

“…It is generally acknowledged that SbCl 3 can readily react with thiourea forming unstable Sb 3+ -thiourea complex. The unstable complex is liable to thermally decompose into Sb 2 S 3 phase under solvothermal condition [18], and the chemical reactions involved in this process can be expressed using the following formula:…”

“…Particularly, thiourea, among various sulfide ion sources, is a widely used and easily available one for synthesizing Sb 2 S 3 crystals via the decomposition of Sb-thiourea complex. For example, Sb 2 S 3 nanocrystals with feather-like, rod-like, flower-like, tube-like and straw-bundled-like morphologies were synthesized by using solvothermal method [18] and microwave [19] and refluxing [20,21] treatment of Sb-thiourea precursor. Polycrystalline Sb 2 S 3 thin films were prepared by spray pyrolysis of Sb-thiourea complex [8,22].…”

A template‐free route for controlled synthesis of dumbbell‐like Sb2S3 microcrystals

“…The cleavage of crystals would appear easily. Qian et al found that a secondary nucleation could be observed on the top surface of the individual crystal [22]. In [17] and [18], people also found that Sb 2 S 3 crystals splitting occurred easily.…”

Tartatric Acid and L‐Cysteine Synergistic‐Assisted Synthesis of Antimony Trisulfide Hierarchical Structures in Aqueous Solution

“…[2] So far, various morphologies and architectures of Sb 2 S 3 nanostructures have been reported, such as microtubes, [3] hollow cones, [4] whiskers, [5] dendritic-like, featherlike microstructures, [6] hollow olivary architectures, [7] nanorod-bundles, [8] and sheaf-like hierarchical nanostructure. [9] Besides the above shapes, Sb 2 S 3 microspheres also have been intensively studied and many efforts have been devoted to their fabrication.…”

“…Cheng et al [10] prepared Sb 2 S 3 microspheres by a one-step, ambienttemperature reaction in ethanol solution. Hu et al [11] used SbCl 3 and NH 2 NHCSNH 2 at 140°C in ethanol solution to gain prism-sphere-like and prickly sphere-like Sb 2 S 3 . Hollow Sb 2 S 3 microspheres [12] were realized by the groups of Shen and Cao through a chemical conversion method and a convenient Ostwald ripening route, respectively.…”
