摘要
用不同于专利的方法合成了磷酸硅锰铝分子筛(MnAPSO-5)的纯相,通过顺磁共振谱、红外光谱、X射线光电子能谱、电子探针波谱分析及晶胞参数测定,确证杂原子锰和硅已进入分子筛骨架。并考察了分子筛的酸性、吸附性能及热稳定性。
The pure Manganese Silicoaluminophosphate molecular sieve was synthesized by hydrother-mal crystallization. The structure of MnAPSO-5 has been researched by means of electron paramagnetic resonance spectra, infrared spectra, XPS, electron probe, XRD. The results show that the atoms of manganese and silicon entered into the framework of MnAPSO- 5 molecular sieve. Their crystal morphology, surface acidity,ability of adsorption and thermal stability were also investigated.
