摘要
采用静态水热法合成了具有AEL结构的硼铝磷酸盐分子筛(BAPO-11),利用XRD、BET、FTIR及SEM等方法对BAPO-11进行了表征.研究结果表明,当活性胶液中的硼和磷的相对含量为0<n(B2O3)/n(P2O5)<0.20时,可以合成出不同硼含量的BAPO-11,其中B为骨架硼,且随活性胶液中的B含量不同,BAPO-11的晶体形貌亦有所不同.
A series of boron aluminophospate molecular sieves （BAPO-11, AEL topology） were synthesized by static hydrothermal method and characterized by XRD, BET, FTIR and SEM techniques. The experimental data show that BAPO-11 molecular sieves with different boron contents were well crystallized when the formal molar ratio of B2O3/P2O5 in the reactive gel was selected in the range of from zero to 0.20. Variation in the crystal morphology of BAPO-11 molecular sieves was observed with the increasing of boron content. And boron substitution in the framework of AIPO4-11 was confirmed by characterization results obtained here.
