Catalytic NO Decomposition on Cu
... Catalytic NOx decomposition remains the most robust strategy for NOx removal from lean combustion effluent streams, because it does not require a reductant. Microporous solids with exchanged cations [1] are among the most active NO decomposition catalysts reported, but their catalytic activity remai ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
