采用浸渍法制备了不同铈负载量的铈/二氧化钛催化剂，并对其在富氧条件下NH3选择性催化还原NO的性能进行了研究。含5%Ce及以上的催化剂在275-400°C的温度范围和50，000 h-1的空速下具有高活性。在本实验条件下，所有催化剂均表现出良好的N2选择性和对SO2和H2O的耐受性。
Samples of cerium supported on titania with different Ce loadings have been prepared by an impregnation method and tested for the selective catalytic reduction of NO by NH3in the presence of excess oxygen. The catalysts with 5% Ce and above had high activity in the temperature range 275–400°C at a space velocity of 50,000h−1. All the catalysts showed an excellent selectivity to N2and high tolerance to SO2and H2O under our test conditions.
