摘要： 以氯化锌和草酸铵为原料,通过沉淀反应制得前驱物二水合草酸锌,再经过热分解,得到20～80nm类球形和立方形的纳米氧化锌·分析了沉淀反应温度、时间、Zn2+初始浓度,以及热分解反应温度、时间对纳米氧化锌粒度和形貌的影响规律·结果表明:增加沉淀反应时间、热分解反应温度和时间,产品粒度均有不同程度的增大,而沉淀反应温度提高,产品粒度先减小后增大·Zn2+初始浓度在0 5mol/L以下时,对粒度影响不大(25nm左右),当达到0 7mol/L时,平均粒径提高到80nm左右·

Abstract: Sphere-like and cubic ZnO nanoparticles were synthesized using ZnCl2 and oxammite as raw materials by way of the precipitation reaction through which the precursor ZnC2O4 · 2H2O was obtained and then pyrolyzed. TEM and XRD results showed that they are of crystalline zincite with grain size 25-80 nm. The TG-DTA test was carried out for the precursor. It was revealed that increasing the reaction time and pyrolysis time/temperature will increase the size of primary particles. On the other hand, increasing reaction temperature (below 90°C) will take opposite effect. When the original concentration of Zn2+ is below 0.5 mol/L the size of the particles change little (25 nm), but when it reaches 0.7 mol/L the size ascends to 80 nm.
