Abstract
The SnS2 hollow nanospheres are successfully fabricated using SnCl4·5H2O, thiourea and urea as raw materials via a mild one-step hydrothermal process. The size of SnS2 hollow nanosphere is about 400 nm, and the shell thickness of it is about 50 nm, consisting of nanoparticles with the size of 3 nm. The formation of such hollow structure could be mainly ascribed to the soft template effect of carbon-dioxide and ammonia bubbles decomposed from urea. The obtained hollow nanospheres possess a higher specific surface area of 142 m2 g−1 compared with that of the SnS2 granular aggregate sample (34 m2 g−1), presenting better cycling stability and rate capability.
