Abstract (en)
[origin: WO2012041921A2] The invention relates to a method for treating a gas containing nitrogen oxides (NOX), comprising a reduction reaction of the nitrogen oxides by a nitrogen-containing reducing agent. The invention is characterised in that the catalyst used for the reduction reaction is a catalytic system containing a composition based on cerium oxide and comprising niobium oxide in a proportion by mass of between 2 and 20 %.
