常规合成层柱粘土首先制备含有稳定结构的多聚羟基阳离子络合物柱化剂,柱化剂与粘土混合时这些稳定的阳离子直接交换到粘土层间,热处理后形成柱子撑开粘土层面构成层柱粘土的规整孔道.钛(IV)水解性强,在水溶液中其物种存在形式仍有争议,我们通过对合成钛层柱粘土(Ti-PILC)交换物种的研究发现钛(IV)物种不稳定,与其它稳定阳离子的造孔作用不同.
Conventional synthetic pillared clay first prepares a polyhydroxyl cation complex pillaring agent with a stable structure. When the pillaring agent is mixed with the clay, the stable cations are directly exchanged into the clay layers, and the pillars are formed after the heat treatment to distort the clay layer. The regular channels of column clay. Titanium (IV) is highly hydrolyzable and its species present in aqueous solution is still in dispute. We have found that species of titanium (IV) are unstable by studying Ti-PILC exchange species , And other stable cation pore function different.
