Abstract

This paper reports a novel family of aluminophosphate based molecular sieves denoted as VPI-5. These molecular sieves are the first to contain pores larger than 10 Å. The large pores of the VPI-5 sieves consist of long channels circumscribed by eighteen membered rings and are capable of adsorbing molecules excluded from other molecular sieves.
