摘要： In the control of pollutants such as NOx in the exhaust gases from internal combustion engines, ozone is reacted with NO to form NO2, which is then reduced catalytically to N2, by reacting NO2 with ammonia. The NO2 produced can react with the particulates of Diesel engine to exhaust gas to regenerate a particulate filter.

摘要： This invention relates to catalyst for use in the control of atmospheric pollution and, in particular to the purification of exhaust gases from internal combustion engines. Specific catalysts of the present invention comprise:(a) ruthenium or an alloy thereof and a metal oxide capable of forming a stable mixed oxide (or "ruthenite") with ruthenium dioxide;(b) a compound formed by ruthenium dioxide and a metal oxide capable of forming a stable mixed oxide (or "ruthenite") with ruthenium dioxide; and(c) a mixed oxide containing ruthenium, the oxide being selected from the group consisting of oxides of the pyrochlore type A.sub.2 B.sub.2 O.sub.7, the perovskite type ABO.sub.3, the ilmenite type B.sub.2 O.sub.3 and the spinel type AB.sub.2 O.sub.4.Particularly good results have been obtained where the platinum/ruthenium ratio is within the range 25 - 95 wt.% platinum and 5 - 75 wt.% ruthenium.
