Ceria(CeO₂) is considered as one of materials for the simultaneous removal of SOx and NOx from flue gas. Ceria was coated on honeycomb and tested for adsorption of SO₂ and reduction of NO with ammonia. Experimental results showed the characteristics similar to copper oxide but reactivity for NO reduction was higher in broader temperature range compared with the latter.
