| Abstract：In this work, nanometer sized ZnO particles were prepared by gas solid phase reaction with ZnSO 4 and NH 4HCO 3. The reaction mixture was at 120℃ for 1h, and then the powder washing with water, and heat treated at 600℃ for 1h. The particles were characterized by XRD, TEM, BET and scattering of light. The results indicate that the average size of nanometer sized particles is around 9.5nm, and average surface area is about 60.05m 2/g. The influence of reaction on the synthesizing process and final pow... |
