Local probes show that framework modification in zeolites occurs on ammonium exchange without calcination
Framework modification involving a change in the Al environment from tetrahedral to octahedral is frequently reported in ammonium-exchanged zeolites after calcination, steaming, acid wash and other harsh treatments. We characterized Na-Y and partially exchanged NH4-Y zeolites by spectroscopic and di...
