The Effect of PVP Addition and Heat-treatment Duration on Zinc Oxide Nanoparticles

Ali Elkhidir Suliman, Yiwen Tang, Zhan Xin and Zhijie Jia
ZnO nanoparticles were prepared by hydrothermal method different size ZnO nanoparticles were obtained by changing the quantity of PVP which was added to optimize the particle size. The effectiveness of PVP on the particle size has been studied. ZnO nano sheets and ZnO nanorods were prepared by heat-treated of ZnO nano particles for different durations. TEM, XRD and SEM were used to investigate the particles size, particles shapes and the transformation process. We found that by adding more PVP we can get smaller size and good dispersion ZnO nanoparticles and the heat-treatment duration affected the shape which resultant from the aggregation of nanoparticles. A completely transformation from Zn(OH)2 face to ZnO face process has been shown.
