Cu-Based and Fe-Based SCR Catalysts

Copper-based catalysts are ideal active ingredients for NH3-SCR catalysts due to their excellent redox ability and suitable acidity. At present, research on copper-based catalysts for denitrification reactions mainly focuses on copper-based molecular sieve catalysts as the main research object. Copper-based molecular sieve catalysts have good activity and N2 selectivity in low-temperature environments, making them a promising medium to low-temperature denitrification catalyst. However, there is relatively little research on copper-based oxide catalysts, and more research is needed.
