摘要：

Vanadium has been introduced into Y zeolite by heating the physical mixture of V2O5 and HY in an airflow containing water vapor. Back ion exchange, FTi.r. and e.p.r. results suggest that ion exchange occurred between protons of zeolite and the (VO)3+ formed during preparation. The zeolite crystallinity is maintained, and the e.p.r. experiments show two different positions in Y zeolite for the entered vanadyl species, one in the supercage and another in the β-cage, neither of them influenced by exposure to air. © 1990.
