摘要
采用水热法,合成了 CoAPO-5分子筛大晶体,通过 X 射线衍射分析、电子显微镜观察形貌、电子探针、热稳定性、红外光谱、X 射线光电子能谱、^(31)P 固体高分辨魔角旋转核磁共振、晶胞参数测定、表面酸性分析等,对其结构和性能进行了研究。
Single crystals of CoAPO-5 molecular sieve are synthesized by hydrothermal
method.The structure and properties as well as related parameters of the unit
cell of single crystals of CoAPO-5 molecular sieve are determined and studied by
means of X-ray diffraction analysis,scanning electron microscopy,electron probe,
thermal stability,infrared spectroscopy,surface acidity,X-ray photoelectron spect-
roscopy,and ^(31)P high resolution magic-angle-spinning solid state nuclear magnetic
resonance.These results illustrate that cobalt atom do situate in CoAPO-5 single
crystal framework.
