通过在二醇溶液中加热Zn（OH）2得到氧化锌（ZnO）纳米颗粒。以乙二醇、1，3-丙二醇和1，4-丁二醇为原料，在308 K以上的温度下对Zn（OH）2进行热处理，可以得到纳米ZnO。特别是当使用乙二醇对Zn（OH）2进行热处理时，得到了平均直径小于20 nm的ZnO纳米粒子分散的稳定溶胶。当加热温度为308 K时，得到了球形二次粒子和ZnO一次粒子。二次颗粒中的孔隙率可以通过用于加热Zn（OH）2的二醇溶液来控制。
Zinc oxide (ZnO) nanoparticles were obtained by heating Zn(OH)2in a diol solution. When ethylene glycol, 1,3-propanediol and 1,4-butanediol were used for the heat treatment of Zn(OH)2, ZnO nanoparticles can be obtained by heating at more than 308 K. In particular, when ethylene glycol was used for the heat treatment of Zn(OH)2, the stable sols with the dispersion of the ZnO nanoparticles whose average diameter was less than 20 nm were obtained. Furthermore, when the heating temperature was 308 K, the spherical secondary particles with ZnO primary nanoparticles were obtained. The porosity in the secondary particles can be controlled by the diol solution used for heating of Zn(OH)2.
