title: Elucidating the nature and reactivity of Ti ions incorporated in the framework of AlPO-5 molecular sieves. New evidence from 31P HYSCORE spectroscopy.
abstract: The incorporation of Ti ions within the framework of aluminophosphate zeotype AlPO-5 and their chemical reactivity is studied by means of CW-EPR, HYSCORE, and UV-vis spectroscopies. Upon reduction, Ti(3+) ions are formed, which exhibit large (31)P hyperfine couplings, providing direct evidence for framework substitution of reducible Ti ions at Al sites.
