Abstract

Comparing with the traditional method to make the tin oxide (SnO ₂) sensor material (hydrolysis of SnCl ₄ in basic solutions), a novel CVD strategy has been investigated to prepare highly sensitive SnO ₂ microspheres. SnCl ₂ was used as the precursor to form SnS ₂ microspheres, which was composed of single-crystal SnS ₂ sheet. Then, the sample was oxidized in air and transformed to polycrystalline SnO ₂ microspheres. BET surface area and BJH pore diameter were measured with nitrogen adsorption at 77.36 K on a Chemsorb-3000 instrument. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results showed the sample had small grain size, which made it highly sensitive to ethanol.
