EXAFS study of hydrated manganese‐exchanged A and Y zeolites

Analyses of the EXAFS of exchanged divalent manganese cations in small pore (A) and large pore (Y) zeolites reveal that the local environments of the cations in the zeolite are similar to the environments of Mn2+ in solution. Further, the EXAFS show no long‐range order about the exchanged cations in the zeolite. The implications of the similarity of complexes in the zeolites and in aqueous solution and the lack of long‐range order about the intrazeolite cations are discussed.
