ABSTRACT:
A class of pillared interlayered clay molecular sieves with large pore size were prepared by cross-linking the regularly interstratified mineral clay. Wherein the cross-linked rectorites possess an extraordinary thermal and hydrothermal stabilities. Said class of pillared interlayered clay molecular sieves are potential commercial catalysts for carbonium-ion type reactions, adsorbents and catalyst carriers.
