Abstract: The present invention is directed towards a catalytic coating comprising a composite oxide which accelerates soot combustion. The oxide is used in a catalytic coating in soot filters for the abatement of noxious pollutants in exhaust gases from combustion processes. A process for the production of catalytic coatings comprising these composite oxides is also given.
