Abstract:

Nano/micron-sized ZnO spheres were fabricated by homogeneous co-precipitation at 75 ℃. The prepared spheres were characterized by X-ray diffraction（XRD）and scanning electron microscope（SEM）. The effect of reaction time and HWP（H₃PW₁₂O₄₀∶HPW）concentration was investigated. The result showed that the ZnO spheres after 3h reaction had uniform sizes and dispersed well when the concentration of Zinc acetate dihydrate，TEA and HPW were 0.025 mol/L，0.100 mol/L and 1.00×10^－3 mol/L respectively.
