The selective catalytic reduction (SCR) of NO with C 3 H 8 was studied over unsulfated and pre-sulfated 1% Pt/β₯-Al 2 O 3 , and 1% Pt-2% Sn/β₯-Al 2 O 3 catalysts. Carbon residues deposited were evaluated on all samples, after 12 h of C 3 H 8 -NO-O 2 -SO 2 reaction. X-ray photoelectron spectra (XPS) we
