Zinc Oxide Nano-materials Synthesis,Structural Characterization,Optical and Catalytic Properties

WEI Gui-ming1,DU Ji-min2,RONG Hao-jie,ZHANG De-jing(1.Library of Anyang Normal University,Anyang,455002,China;2.College of Chemistry and Chemical Engineering,Anyang Normal University, Anyang,455002,China)  
The different forms of zinc oxide nanomaterials were synthesized by using Zn(AC)2·2H2O and NaOH as reaction precursors and cetyl lycine brominated ammonium(CTAB) for surfactant with the hydrothermal method.The resultant samples were characterized with X-ray diffraction diffractometer(XRD),Infrared Spectrometer(IR) and field emission scanning electron microscope.The optical properties of obtained ZnO nanomaterials with different shapes were recorded by photometric Uv-vis and PL,indicating the extstence of crystalline defects.In order to evaluate the performance of ZnO catalyst,nanometer ZnO with various morphologies were used as catalyst for esterification reaction of acetic acid and n-butyl alcohol via a refluxing method.On the base of catalytically experiments,the nanometer ZnO on the esterification reaction was found very good catalytic behavior with transition rate up to 85.79%.Meanwhile,the morphologies of resultant ZnO nanomaterials have an effect on the transition rate of acetic acid and n-butyl alcohol esterification due to their different surface areas.
