摘要
采用室温固相反应法合成了(NH4)6P2W18O62·12H2O纳米粒子.通过元素分析、红外光谱分析、X射线衍射、透射电镜等对其进行了表征.结果表明,制备的纳米粒子仍保留着杂多阴离子的Dawson结构,具有Dawson结构的特征衍射峰.制备的粉体粒子平均粒径为32nm.用此方法合成多金属氧酸盐的纳米粒子,避免了产生大量反应液而造成的环境污染,优于其他方法.
The nano particle (NH_4)_6P_2W_(18)O_(62)·12H_2O with Dawson structure has been synthesized by solid-phase reaction at room temperature. It has been characterized by elemental analysis, IR, XRD and TEM techniques . The results show that the polyoxometalate nanoparticles still exhibit Dawson structure. Its average size is about 32 nm. This synthesis doesn't cause environmental pollution.
