摘要：

A novel and high performance silver loaded hydroxyapatite (HAp) catalyst for the selective catalytic reduction (SCR) of NO(x) by propene is reported for the first time. The catalysts with variable silver contents have been prepared and characterized extensively by different techniques such as XRD, XPS, BET-surface area, TPR, TPD and ICP analyses. The DeNO(x) activities of these catalysts are measured at reaction temperature ranged from 250 to 500 degrees C. The 1.5 wt.% Ag/HAp is found to be best among all the catalysts studied showing about 70% conversion and 60% selectivity towards N(2) formation at 375 degrees C in oxygen rich atmosphere.
