The attention is centered on Co and Fe species planted in pentasil ring zeolites of various topologies, specifically on Co-beta and Fe-oxo species in zeolites, exhibiting stable SCR-Nox activity under presence of high excess of water vapor existing in real exhaust gases from combusion processes. Also participation of the protonic, Al-Lewis sites and specific Fe-oxo sites is analyzed with respect to these redox reactions. Workplace J.
