CATALYSTS AND METHODS OF DECOMPOSING NITROGEN OXIDES

摘要

This invention relutes to catalysts which may be used in the purification of air and other gaseous media. More particularly, the invention relates to catalysts which may be used in the decomposition of one or more of the oxides of nitrogen comprising a mixed oxide of iron and cobalt selected from the group consisiting of (a) where x normally has values o?x?1 - and (b) where x normally has values i?x??.
