Abstract

‘Magic-angle-spinning’ NMR has revealed fresh insights into the atomic structure of the polymorph of silica, silicalite, which has exceptional absorptive properties. There is evidence that highly crystalline variants of silicalite contain 24 distinct tetrahedral locations, populated principally by Si4+ ions, and that, contrary to what was originally thought, aluminium is also present, in at least two kinds of environments, in the tetrahedral framework. The silicalite structure is shown to be essentially indistinguishable from that of the siliceous zeolite catalyst ZSM-5.
