The Pd/FeTi catalyst showed higher H-2-SCR activity compared to Pd/Ti and Pd/Fe catalysts, mainly due to the formation of FeTi solid solution and highly dispersed Pd on the support.
Selective catalytic reduction (SCR) of NOx by H-2 over Pd/Ti, Pd/Fe and Pd/FeTi catalysts was systematically investigated. Compared with Pd/Ti and Pd/Fe catalysts, Pd/FeTi catalyst exhibited higher H-2-SCR activity and the optimal ratio of Fe/Ti is 1. Over Pd/FeTi catalysts FeTi solid solution is formed, and Pd is highly dispersed on the support. XPS analysis showed that there is strong interaction among Pd, Fe and Ti species. In-situ DRIFTS results revealed that more and new adsorbed NOx species, which are reactive to reacting with H-2, formed over Pd/FeTi. All these factors account for the improved H-2-SCR activity of Pd/FeTi catalyst.
