Microwave-assisted synthesis and characterization of single dimension ZnO nanorods

ZnO nanorods assembled in flower shaped morphology have been successfully synthesized by a straightforward microwave technique in a very short duration using zinc acetate Zn(CH3COO)2·2H2O and HMTA as reactants.The effects of the ratio of Zn(CH3COO)2·2H2O and HMTA、terminal pH values and time of microwave irradiation on the crystal phase,morphology and particle size distribution of the obtained ZnO nanopowers were investigated.The synthesized nanorods were characterized by X ray diffraction(XRD),scanning electron microscopy(SEM)and field emission scanning electron microscopy(FESEM).The results revealed that the ZnO nanorods had pure wurtzite structure,its diameter and length of the rods were within 30—45nm(tip diameter—10nm)and 1—2μm respectively.
