Catalysis is so exhausting : A CeTi mixed oxide catalyst prepared by a homogeneous precipitation method presented excellent NH 3 ‐SCR activity with nearly 100 % NO x conversion in a temperature range of 200–350 °C (the main temperature range of diesel engine exhaust) at a space velocity of 50 000 h −1 and displayed prominent performance even under a high space velocity of 150 000 h −1 .
