Aluminosilicate or silicoaluminophosphate molecular sieve/manganese octahedral molecular sieve as catalysts for treating exhaust gas

摘要

Catalysts and articles useful for selective catalytic reduction (SCR) and other exhaust gas treatments are disclosed. The catalysts comprise an octahedral molecular sieve (OMS) comprising manganese oxide and an aluminosilicate and/or silicoaluminophosphate large-pore or medium-pore molecular sieve.
