Wilson等的研究表明,AlPO_4-n分子筛是由AlO_4、PO_4四面体交替组成的中性骨架,没有离子交换性和B酸酸性,故其应用受到限制.将一些具有良好催化活性的金属离子引入AIPO_4-n分子筛,对改变其中性骨架是很有意义的.FeAPO-5,11等分子筛已见报道,但FeAPO-44的合成及研究尚无文献报道.本文用水热法合成了FeAPO-44分子筛纯相,并对其结构和性能进行了研究.
Wilson et al. Have shown that AlPO 4-n molecular sieve is a neutral framework composed of alternating AlO 4 and PO 4 tetrahedra and has no limitation of ion exchange and B acidity, so some metal ions with good catalytic activity are introduced into AIPO_4 -n molecular sieve, it is meaningful to change its neutral framework.FeAPO-5, 11 and other molecular sieves have been reported, but the synthesis and research of FeAPO-44 have not been reported in literature.In this paper, hydrothermal synthesis of FeAPO-44 molecular sieve pure Phase, and its structure and performance were studied.
