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 UVvis spectroscopies. Upon reduction, Ti3+ ions are formed, which exhibit large 31P hyperfine couplings, providing direct evidence for framework substitution of reducible Ti ions at Al sites.
