Large-scale synthesis of Sb<inf>2</inf>S<inf>3</inf> spikes by hydrothermal reaction

Abstract

Spikes of Sb 2 S 3 (antimony sulfide) were synthesized by hydrothermal reaction at 100–200 °C for 6–48 h. By using X-ray diffraction (XRD), selected area electron diffraction (SAED), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), high resolution TEM (HRTEM) and UV-vis absorption spectroscopy, the products were specified as orthorhombic Sb 2 S 3 in the shape of spikes, with their growths in the [001] direction and E g of 5.40 eV. A diffraction pattern was also simulated, and was in good accordance with the SAED pattern obtained from the experiment.
