Abstract
A selective catalytic reduction (SCR) catalyst composition effective in the abatement of nitrogen oxides (NO) is provided. The SCR catalyst composition significantly increases the conversion of NOrelative to a Cu-chabazite reference catalyst composition at any temperature, and especially at low temperatures. A catalyst article, an exhaust gas treatment system, and a method of treating an exhaust gas stream, each including the SCR catalyst composition of the invention, are also provided. The SCR catalyst composition is particularly useful for treatment of exhaust from a lean-burn engine.
