Cyclic microwave assisted synthesis of Sb2S3 dumb-bells using polyvinylpyrrolidone as a template and splitting agent

The Photocatalytic Application of Semiconductor Stibnite Nanostructure Synthesized via a Simple Microwave-Assisted Approach in Propylene Glycol for Degradation of Dye Pollutants and its Optical Property

“…3 . Each individual nanorod growing along the [001] direction [ 30 ]—in accordance with the growth direction identified by Ota et al [ 25 ], Kavinchan et al [ 26 ], and Wang et al [ 31 ]. The SAED pattern shows a systematic array of white spots of orthorhombic phase of Sb 2 S 3 single crystal, corresponding to the diffraction pattern obtained by simulation [ 30 ].…”

“…Thus, the growth direction is preferential along the [001] direction [ 39 ]. The crystal splitting is also associated with fast crystal growth, due to the super saturation that exceeds a certain critical value [ 26 , 39 , 40 ]. In this work, HEC was used as a soft template and capping agent—composed of long macromolecules with a number of hydroxyl groups.…”

“…The crystal splitting is also associated with the sudden crystal growth, due to the saturated solution exceeding a certain critical value [ 39 , 40 ]. Comparing the previous researches, nanorods synthesized using sodium dodecyl sulfate (SDS) as a surfactant by Ota et al [ 25 ], the double flower-like microcrystal using dodecyltrimethylammonium bromide (DTAB) as a surfactant by Wu et al [ 41 ], the dumb-bells using polyvinylpyrrolidone as a template by Kavinchan et al [ 26 ], and nanowires using polyethylene glycol with molecular weight of 6 kDa (PEG-6000) by Wang et al [ 31 ], the present sheaf-like structures synthesized using HEC as capping agent are more beautiful—affected by the stability and reliability of using polymers as templates [ 29 ].

“…Herein, semiconducting photocatalysts of main group metal chalcogenide A 2 X 3 (A = As, Sb, Bi; X = S, Se, Te), such as Sb 2 S 3 or stibnite, have been studied intensively due to their numerous applications including optoelectronic, thermo-electric technologies, solar energy utilization, and semiconducting photocatalyst [ 23 – 25 ]. Different approaches were used for synthesizing of Sb 2 S 3 : refluxing [ 23 ], spray pyrolysis [ 24 ], hydrothermal process [ 25 ], and microwave-assisted synthesis [ 26 ]. In this research, microwave-assisted synthesis in a facile solution-phase method was used for synthesizing Sb 2 S 3 .…”

Facile Hydrothermal Synthesis of Sb2S3 Nanorods and Their Magnetic and Electrochemical Properties

“…[4][5][6] As a well known layer-structured direct bandgap semiconductor, antimony sulfide (Sb 2 S 3 ) has drawn intensive attention due to its proven and potential applications in photovoltaic, solar cells, optical, and superconductor nanodevices. So far, a series of Sb 2 S 3 nanostructures, including simple one-dimensional (1D) nanostructures such as nanorods, 7,8 nanowires, [9][10][11] nanotubes, 12 and some complex nanostructures, such as two-dimensional (2D) and three-dimensional (3D) nanostructures including nanoplates, 13 hollow olivary, 14 microspheres, 15,16 and hierarchical nanostructures 17,18 have been prepared via different methods including the hydrothermal or solvothermal method, sonochemical techniques, and cyclic microwave radiation process. However, most of these methods mentioned above for preparation of Sb 2 S 3 nanostructures generally require high reaction temperature, surfactants or templates, which will increase the complexity and infeasibility.…”
