摘要
综述新型有机金属骨架材料和复合金属骨架材料催化剂在选择性催化还原氮氧化物方面的研究进展,讨论金属有机骨架材料催化剂的低温脱硝活性和抗硫抗水性能,介绍脱硝反应过程中氮氧化物的反应机理。针对金属有机骨架材料表现出的良好低温脱硝活性,认为其有可能替代传统脱硝催化剂。
The research progresses on new type metal organic materials( MOFs) and composed MOFs catalyst for selective catalytic reduction( SCR) of NOx were reviewed. Low temperature activity,performance on resistance to SO_2 and H_2 O and the mechanism in the SCR reaction over MOFs catalysts havd been discussed. The MOFs catalysts were considered to be the potential alternative for the conventional SCR catalysts for its good deNOx catalytic activity at low temperature.
