Abstract

The performances of selective catalytic reduction (SCR) by CO/H2 over two Pd/TiO2/Al2O3 catalysts prepared from PdCl2 and Pd(NO3)2 precursors were compared. The catalytic activities (NOx conversion and N2 yield) were measured on these two catalysts. The catalytic properties of the prepared catalysts were studied by various characterization techniques such as BET, CO-chemisorption, TEM, XPS, and TPD. The Pd precursors influenced the Pd particle distribution, resulting in different catalytic activities.
