Abstract

By means of an EPR investigation of Mo5+ ions introduced into NaY zeolites by solid-state reactions, the location and coordination of Mo5+ in zeolites were investigated. Two different locations, free and distorted tetrahedral, were found. The molecular orbital coefficient, beta(2), and the effective charge, Q, for the Mo5+ ions in a distorted tetrahedral structure were calculated and interpreted.
