多孔黏土异质结构材料(PCHs)是以长链烷基铵为模板剂,以黏土矿物为基体制备的一类柱撑材料。PCHs独特的孔径分布范围弥补了微孔性柱撑黏土矿物和介孔硅之间的孔径分布间隙。其有希望成为良好的吸附剂、催化剂、载体或合成其他多孔材料的模板。因此,PCHs的成孔机制和有效的结构控制尤为重要。长期以来,PCHs的成孔机制一直参照介孔硅的分子
Porous clay heterostructures (PCHs) are a type of pillared material made of long-chain alkylammonium as a template and clay minerals as matrix. The unique pore size distribution of PCHs makes up for the pore size distribution gap between microporous pillared clay minerals and mesoporous silica. It is promising to be a good adsorbent, catalyst, support or template for the synthesis of other porous materials. Therefore, PCHs pore forming mechanism and effective structural control is particularly important. For a long time, the mechanism of pore formation of PCHs has been with reference to the molecules of mesoporous silica
