在磷酸锰铝分子筛MnAPO-5纯相合成的基础上,研究了它的结构和物化性能。晶胞参数和红外光谱的测定结果表明它具有AlPO_4-5型分子筛的结构;顺磁共振和电子探针能谱分析及组成分析表明Mn(Ⅱ)结合到分子筛的骨架上。同时对其吸附性能,热稳定性表面酸性进行了研究。
Based on the pure phase synthesis of manganese aluminate molecular sieve MnAPO-5, its structure and physicochemical properties were studied. The results of unit cell parameters and infrared spectra show that it has the structure of AlPO_4-5 molecular sieve. The analysis of energy spectrum and compositional analysis of paramagnetic resonance and electron probe show that Mn (Ⅱ) is bound to the framework of molecular sieve. At the same time, its adsorption properties, thermal stability of the surface acidity were studied.
