磷酸锰钴铝(MnCoAPO—5)分子筛的合成与表征

THE SYNTHESIS AND CHARACTERIZATION OF MANGANESE COBALT ALUMINOPHOSPHATE (MnCoAPO-5) MOLECULE SIEVE

以三乙醇胺作模板剂,用水热法合成了MnCoAPO-5分子筛。用X射线衍射,电子探针,红外光谱等方法进行了结构研究,并测定了其晶胞参数和化学组成,同时对此分子筛的晶体形貌,热稳定性,吸附性能和比表面等进行了研究。证明锰和钴同时进入AlPO-5分子筛骨架而未改变结构类型。

Manganese Cobalt Aluminophosphate( MnCoAPO - 5)mo lecule sieve was synthesized by the hydrothermal method in the presence of triethanolamine which acts as the template. The crystal structure of MnCoAPO-5 has been studied by means of X-ray diffraotion, electron probe and infrared spectra. Some properties of MnCoAPO-5 such as adsorption isotherms, thermal stability have been investigated. All the results illustrate that Manganese and Cobalt enter simul - taneously the ALPO_4-5 molecule sieve framework without disrupting the microporous framework.
