Flowerlike MoS2 nanoparticles: solvothermal synthesis and characterization

Abstract

Flowerlike MoS 2 nanoparticles have been successfully synthesized through a mild solvothermal reaction with the aid of ethanol aqueous solution, and the samples have been characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and low temperature nitrogen adsorption-desorption. The nanometer flower MoS 2 is composed of ultrathin nanosheets of approximately 10 nanometers in thickness. The influence of the reaction temperature and the reaction time on the formation of the flowerlike MoS 2 nanoparticles were evaluated. The optimal experimental conditions were determined as follows: the molar ratio of 1∶1 between ethanol and water, the reaction temperature of 190°C, and the reaction time of 24 h.

Nanostructured molybdenum dichalcogenides: a review

“…Materials Advances 500 1C. 62 The authors observed that a lower temperature and reaction time leads to formation of MoO 2 impurities. Several researchers have also reported synthesis of nano-MoSe 2 by the solvothermal method using an autoclave.…”

“…Similarly, flower like nanoparticles composed of ultrathin nanosheets of MoS 2 have been reported by use of the sodium molybdate, thiourea and hydroxylamine hydrochloride mixture (1 : 2 : 2 molar ratio) in an autoclave heated for 24 h at 190 °C, followed by annealing for 5 h at 500 °C. 62 The authors observed that a lower temperature and reaction time leads to formation of MoO 2 impurities.…”

Reverse micelle assisted hydrothermal reaction route for the synthesis of homogenous MoS2 nanospheres

“…MoS 2 nanostructures of various shapes such as 2D sheets [7], nanoparticles (NP) [8], nanospheres (NS) [9], nanorods [10], nanoflowers [11], and quantum dots [12] are gaining attention over the past decade and are prepared by methods such as exfoliation [13], chemical vapor deposition(CVD) [14], hydrothermal/solvothermal methods [15], gas-phase synthesis [16], sol-gel methods [17] etc. The synthesis of MoS 2 NS is generally carried out using hydro/solvothermal methods at high temperatures using various precursors in the presence of a reducing agent, for e.g.…”
