Hydrothermal synthesis of zinc oxide (ZnO) microparticle
Zinc oxide (ZnO) microparticle was synthesized by hydrothermal route using zinc acetate and ammonium hydroxide as the starting precursors in the mole ratio of 1:6. The final mixture solution was adjust with pH of 9 and treated in PTFE-line autoclave at 100 °C for 2, 4 and 6 h. The precipitate was wa...

| Summary: | Zinc oxide (ZnO) microparticle was synthesized by hydrothermal route using zinc acetate and ammonium hydroxide as the starting precursors in the mole ratio of 1:6. The final mixture solution was adjust with pH of 9 and treated in PTFE-line autoclave at 100 °C for 2, 4 and 6 h. The precipitate was washed with deionized water until the final pH solution of 7 and then dried at 100 °C for 4h. The phase structure was examined by X-ray diffraction (XRD). A single phase hexagonal structure was obtained without calcination step. Microstructure was investigated by scanning electron microscopy (SEM). The particle size of ZnO was in the range of 0.15-1.5 μm with irregular in shape. The chemical composition was identified by energy dispersive X-ray spectroscopy (EDXS). The elemental composition of ZnO showed the characteristic X-ray energy value as follows: zinc of Lα = 1.012 keV, Kα = 8.630 keV and Kβ = 9.570 keV and oxygen of Kα = 0.525 keV, respectively. © 2008 Trans Tech Publications, Switzerland. |
