摘要:

75 下采用均相沉淀法制备了ZnO微球,并运用XRDSEM等方法表征了制得的样品,考察了反应时间和磷钨酸浓度对ZnO形貌的影响,讨论了纳米氧化锌的生长机理。结果表明:乙酸锌浓度为0.025 mol/L,三乙醇胺(TEA)浓度为0.100 mol/L,催化剂HPW浓度为1.00×103 mol/L条件下,反应2 h制得的ZnO微球粒径均一,分散性良好。

Abstract:

Nano/micron-sized ZnO spheres were fabricated by homogeneous co-precipitation at 75 . The prepared spheres were characterized by X-ray diffractionXRDand scanning electron microscopeSEM. The effect of reaction time and HWPH3PW12O40HPWconcentration was investigated. The result showed that the ZnO spheres after 3h reaction had uniform sizes and dispersed well when the concentration of Zinc acetate dihydrateTEA and HPW were 0.025 mol/L0.100 mol/L and 1.00×103 mol/L respectively.
