Single-crystalline SnS2nano-belts fabricated by a novel hydrothermal method

Abstract

SnS₂ nano-belts have been prepared by a novel thioglycolic acid (TGA) assisted hydrothermal method. X-ray diffraction reveals that the SnS₂ nano-belts are of hexagonal structure and well crystallized. Transmission electron microscopy observation shows that the SnS₂ nano-belts have a width of 80–160 nm and a length of up to several micrometres, and high-resolution transmission electron microscopy further identifies that the SnS₂ nano-belts are single-crystalline in nature. A preliminary mechanism for the TGA-assisted hydrothermal synthesis of SnS₂ nano-belts is presented.
