摘要
采用水热合成与离子交换方法,合成了10种Keggin结构杂多阴离子柱撑粘土ZnAl—XW_(12-n)M_n,通过XRD、IR、UV—Vis、ESR和DTA等手段系统研究了它们的结构,讨论了杂多阴离子在层间与层板的相互作用以及这种作用对柱撑粘土的热稳定性、酸催化活性等性质的影响。
The anionic clays pillared by heteropolyoxometalate, ZnAl- XW12-nMn, were synthesized by means of hydrothermal ion -exchange reactions,and characterized by XRD,IR,UV -Vis,ESR and DTA spectra. The interaction betweenthe layers and pillars, and the influence of this interaction on heat stability and acid catalytic activity of pillared clay were investigated.
