磷酸铁锰铝分子筛的合成和鉴定

Synthesis and Identification of FeMnAPO-5 Molecular Sieve

用水热法合成了磷酸铁锰铝分子筛(FeMnAPO-5)。通过红外光谱、穆斯堡尔谱等进行了结构和性能研究。实验结果表明,铁和锰已进入了分子筛骨架。

The FeMnAPO-5 molecular Sieve was synthesized by hydrothermal method. The structure and properties of FeMnAPO-5 were researched by means of infrared spectra, Mossbauer spectroscopy, high resolution magic-angle-spining solid state ~(31)p and ~(27)Al nuclear magnetic resonance, electron probe, parameters of the unite cell determination, DTA, TG. SEM analysis indicated that its crystal growth were perfect. After adsorption of pyridin the IR spectra showed the presence of both Lewis and Bronsted acid sites. These results illustrate that ferrum and manganese enter into the framework of FeMnAPO-5 molecular sieve.
