Abstract
Calcination of as-synthesized or ammonium-exchanged forms of zeolite BETA induces an extensive loss of framework aluminium evidenced by27Al MAS NMR, XRD and FTIR spectroscopies. Treatment of the calcined solids in ammonium nitrate restores the tetrahedral Al sites. Material balances show that the latter process is quantitative.
