Synthesis of Nanometer ZnO Particles by Directly Precipitation Method

Nanometer ZnO particles were synthesized by the homogeneous precipitation method from urea and zinc nitrate. TEM analysis shows that nanometer ZnO particles obtained are in the nanosize range of 50nm; BET analysis shows that the specific surface area of the ZnO particles is 25.6m2/g; XRD analysis shows the crystalline of the nanometer ZnO particles is in the hexagonal structure; the formation mechanism of nanometer ZnO particles was concluded by the analysis of XRD, IR and TG-DSC.
