摘要

Composition comprises an aluminosilicate zeolite and a titano-(silico)-alumino-phosphate, where both the aluminosilicate zeolite and the titano-(silico)-alumino-phosphate comprise at least one transition metal, which is iron, copper, manganese, cobalt, chromium, vanadium or molybdenum. An independent claim is included for the selective catalytic conversion of nitrogen containing compound in exhaust gas flow, where the composition is used the catalyst.
