摘要: 以七水硫酸锌和碳酸氢钠为原料,在超快速混合微反应器中合成氧化锌前驱体碱式碳酸锌,再通过焙烧获得纳米氧化锌。考察了各操作条件对纳米氧化锌颗粒制备的影响,采用TEM、XRD、BET等手段对所得的样品做了表征。结果表明,采用快速沉淀法,通过超快速混合微反应器可实现纳米氧化锌的可控制备,所得纳米氧化锌平均粒径为14~55 nm,晶型为六方晶系结构,样品粒径分布窄,分散性良好。

Abstract: The precursor of ZnO,basic zinc carbonate was prepared with zinc sulfate heptahydrate and sodium bicarbonate as raw materials in super rapid mixing microreactor.Then the nano-ZnO was prepared by calcinations.The effects of operating conditions were systematically investigated.The samples were characterized by TEM,XRD,and BET.The results indicated that particle size could be controlled with the rapidfast precipitation method in a super rapid mixing microreactor.The structure of the nano?鄄ZnO prepared belonged to hexagonal structure with average diameters range of 14~55 nm.The size distribution of the sample was narrow with good dispersibility.

Key words: microreactor, nano-ZnO, mass transfer
