Abstract
The present invention provides a catalyst for production of nitric oxide from ammonia and oxygen. The catalyst has the composition A((n+1)−x)BxC(n(1−y))DnyO(3n+1)+d, wherein A is a lanthanide (La, Gd, Nd, Sm) or yttrium, B is an alkaline-earth cation (Ca, Sr or Ba), C is Fe and D is Cr, Mn, Ni, Ce, Ti, Co or Mg, wherein A, B, C and D are selected independent of each other. The catalyst has a high selectivity towards nitric oxide and a low ignition temperature in the reactor. Further the present invention relates to a method for the production of gas comprising nitric oxide by the catalyst of the present invention. The produced gas has a very low content of nitrous oxide.
