3D SnS2 hierarchical micro-flowers were successfully synthesized by a hydrothermal method with ZnSn(OH)6 hollow nanospheres as precursor. The 3D hierarchical microstructure with large specific surface area was obtained by self-assembling individual 2D nanometer sized sub-units. The architectures, morphologies and gas-sensing performances of the products were characterized and it was found that sensors based on SnS2 micro-flowers had a relatively high response value to 50 ppm ammonia gas at 160 °C, with response and recovery times of approximately 4 s and 15 s, respectively. The good gas-performance to low-concentration of ammonia is attributed to the structure of SnS2 which possessed a large surface area and void.
