Abstract: A catalyst for use in the selective catalytic reduction (SCR) of nitrogen oxides. The catalyst comprises a ceramic candle filter substrate and a coating. The coating comprises an oxidic metal carrier comprising an oxide of titanium and a catalytic metal oxide which comprises an oxide of vanadium. The mass ratio of vanadium/titanium is 0.03 to 0.27, the mass ratio being calculated based on the mass of vanadium metal and titanium metal. The catalyst comprises from about 1 to about 10% by weight of the catalytically active material. The catalytic metal oxide is adsorbed onto the surface of the oxidic metal carrier.
