Abstract

Prolonged heat treatment of highly siliceous, template-free ZSM-5 containing Na+ or K+ causes improvement of the lattice structure, migration of alkaline ions to the outer layers of the zeolite particles as shown by XPS and an increased isolation of = Si–ONa sites from = Si–OH sites, as shown by 29Si CP MAS NMR analyses of silylated products
