the surface region upon activation
of Cu–SAPO-34 leads to a several-fold increase in catalytic
activity for the selective catalytic reduction of NOx with NH3. The temperatures required for the activation
are higher than normal calcination temperatures and lead to a homogeneous
transition metal distribution that renders Cu–SAPO-34 an industrially
promising candidate for NOx removal.
