Recent advances in copper-based zeolite catalysts with low-temperature activity for the selective catalytic reduction of NOx with hydrocarbons

Abstract

NOx, as the main air pollutant in the atmosphere, its elimination has attracted wide attention. Several technologies for eliminating NOx have been investigated by some researchers, and the selective catalytic reduction (SCR) of NOx with hydrocarbons has been proven to be an efficacious denitrification technology. Studies have suggested that excellent catalytic performances at low temperatures can be obtained over copper-based zeolite catalysts for HC-SCR. This review summarized the development of copper-based zeolite catalysts for HC-SCR and elaborated the synthesis methods, low-temperature catalytic performance, and reaction mechanism of the catalysts with different compositions and structures. The purpose of this review is to highlight (1) the structure–activity relationship of copper-based zeolite catalysts; (2) the main factors affecting the low-temperature catalytic activity; (3) the HC-SCR reaction mechanism of the copper-based zeolite catalysts; and (4) the design strategies for the copper-based zeolite catalysts with excellent low-temperature catalytic activity for HC-SCR.
