Title
Copper loaded hydroxyapatite catalyst for selective catalytic reduction of nitric oxide with ammonia
Abstract

Copper loaded hydroxyapatite prepared by ion exchange were characterized by XRD, FTIR, BET, UV–vis, H2-TPR and evaluated in the selective catalytic reduction of NO by NH3 under oxidizing atmosphere. The Cu-Hap catalysts, without the libethenite phase presence, have been found to be active, and selective in the NH3-SCR process. The highly dispersed CuO clusters on Ca-Hap surfaces were responsible for the NO conversion in the low temperature range in the NO-SCR with NH3. The presence of 2.5% of H2O in the feed mixture strongly affects the NO conversion in the whole temperature range.
