摘要: 合成了6种两价金属磷酸铝分子筛的纯相MeAPO-5(Me=Mg2+、Fe2+、Co2+、Ni2+、Mn2+、Zn2+)。通过测定晶胞参数、IR光谱、XPS、DTA、ESR、Mssbauer谱、MASNMR谱及电子探针分析,确证了Me2+已进入分子筛骨架,并讨论了它们之间的规律性。

Abstract: The pure MeAPO-5 type molecular sieve was synthesized [Me=Mg( Ⅱ ), Fe( Ⅱ ,Ⅲ ), Co ( Ⅱ ), Ni(Ⅱ ), Zn( Ⅱ ), Mn( Ⅱ )] by hydrothermal method. Their ability of adsorption, thermal stability and structure were also investigated by means of XRD, IR, XPS, ESR, Mossbauer, electron probe and MAS NMR. The results show that the structure of MeAPO-5 molecular sieve are AlPO4-5 type and Metal atom enters the framework of MeAPO-5 molecular sieve.
