The catalyst prepared using solid-state exchange showed higher activity and selectivity to acetonitrile. Catalysts tested in the ammoxidation of ethylene were previously characterized by chemical analysis, XRD, N2-BET measurements and FTIR. TPD of ammonia and FTIR of pyridine used as probe molecule showed that solid-state ion exchange of H-ZSM-5 with cobalt generates new Lewis acid sites which seem to play a role in the ammoxidation reaction.
