✦ Synopsis

A novel Ce-P-O catalyst for the selective catalytic reduction of NO with NH 3 was synthesized. The Ce-P-O catalyst was calcined at 500 °C and showed higher deNO x activity (NO conversion > 90%) with the temperature range of 300-550 °C and at GHSV = 20 000 h -1 . The NO conversion was not significantly affected by the presence of H 2 O and SO 2 . By comparison with the commercial V-W-Ti catalyst, the Ce-P-O catalyst exhibited better resistance to deactivation due to K 2 O poisoning.
