title: Hydrothermal stability enhancement by sequential ion-exchange of rare earth metals on Fe/BEA zeolites used as NO reduction catalysts.
abstract: An addition of rare earth metals with trivalent cation radii of 1.05-1.15 Å to Fe/BEA zeolites improves hydrothermal stability for selective catalytic reduction of NO by NH(3).
