本文以二水合醋酸锌(ZnAc2·HO)和氢氧化钠(NaOH)为原料,采用水热法在170℃反应12h合成了直径约为2μ22m的球状ZnO微晶。利用XRD、FESEM对产品的物相和形貌进行了表征和分析,结果表明该球状ZnO微晶为纤锌矿结构,ZnO微球是由50-100nm的ZnO纳米颗粒自组装构成的。
In this paper, spherical ZnO crystallites with a diameter of about 2μ22m were synthesized by the reaction of zinc acetate dihydrate (ZnAc2 · HO) and sodium hydroxide (NaOH) with hydrothermal method at 170 ℃ for 12h. The phase and morphology of the products were characterized and analyzed by XRD and FESEM. The results show that the spherical ZnO crystallites are wurtzite structure and the ZnO microspheres are composed of 50-100 nm ZnO nanoparticles.
