摘要
杂多阴离子柱撑粘土是一类新型层柱催化材料［１］．本文采用水热合成与离子交换方法首次将三取代Ｋｅｇｇｉｎ结构杂多阴离子α－［ＳｉＷ９Ｏ３７Ｍ３（Ｈ２Ｏ）３］ｎ－（简写为ＳｉＷ９Ｍ３，Ｍ＝Ｍｎ２＋，Ｃｒ３＋，Ｔｉ３＋，Ｆｅ３＋）嵌入到Ｚｎ－Ａｌ型阴离子粘...
A new type of layered materials pillared by heteropolyanions SiW 9M 3(M=Mn 2+ , Cr 3+ , Ti 3+ , Fe 3+ ) were synthesized by means of ion exchange reaction and characterized with elementary analysis, XRD, IR and DTA. The experiments showed that this pillared layered materials had higher catalytic activity for the epoxidation of maleic acid with H 2O 2.
