Abstract: Zinc oxide has been synthesized under low temperature and hydrothermal condition,with Zn(NO3)2•6H2O and NaOH as raw materials and sodium dodecylbenzene sulphonate(SDBS)as surfactant.Based on the prepared ZnO,Ag+ was reduced into Ag particles to decorate ZnO,by glucose as reducing agent under magnetically stirring.The ZnO powder and the decorated ZnO powder were characterized by X-ray diffraction(XRD),scanning electron microscope(SEM),and transmission electron microscope (TEM).Results showed that the ZnO is a kind of needle-like nanowhisker,and the decorated ZnO is Ag nanoparticle-decorated ZnO(Ag NPs/ZnO).A possible formation mechanism of Ag NPs/ZnO was also discussed. 
