Abstract:
Certain catalytic articles, systems or methods provide for excellent NOx conversion and are especially suitable for low temperature NOx conversion. The articles, systems and methods are suitable for instance for the treatment of exhaust gas of diesel engines. Certain articles or systems contain an upstream SCR composition and a downstream LNT composition. The substrate(s) may advantageously be electrically heated.
