Porous clay heterostructures prepared by gallery templated synthesis

摘要

A porous clay heterostructure of a 2:1 layered silicate prepared by a gallery templated synthesis method is described. The method uses an inorganic oxide, a neutral amine surf surfactant and a quaternary onium ion surfactant in the galleries of the 2:1 layered silicate. The structure is then calcined to remove the surfactants which act as a template to produce the porous clay heterostructure. The structure is useful for cracking catalysts, molecular sieves and adsorbents.
