WebThe key step of the NH 3 –SCR reaction over the catalyst at low temperatures was the formation of nitrate on the Cu sites. However, NO 2, with its larger kinetic diameter, could not form nitrate species on the Cu sites efficiently, and part of these molecules formed NH 4 NO 3 in combination with NH 4+ on the Brønsted acid sites.
