PREPARATION AND CHARACTERIZATION OF ELECTRIC ZAO NANOPARTICLES

The white good dispersion zinc aluminium oxide (ZAO) nanoparticles were efficiently prepared by solid phase synthesis method. The morphologies, structures, photoelectricity of the ZAO nanoparticles and the thermochemistry behavior of the precursor were analyzed by TEM, XRD, UV-vis and TG, etc. The phytotoxicity properties of the ZAO nanoparticles were researched for the first time. The results show that the ZAO nanoparticles have a strong inhibition of seed germination and root growth. The biological toxicity of ZAO nanoparticle reduces along with the enlargement of nanoparticle size.
