Catalytic Activities of Bimetallic Catalysts for Low Temperature Water Gas Shift Reaction	2016	6	.htm	application/pdf	3307	90	38	Comparative studies, on the activity of ceria/zirconia supported noble metals catalysts, showed the highest activity of platinum in the temperature range 473-593 K (Radhakrishnan et al., 2006), moreover in our previous studies the role of the support was investigated (Palma et al., 2014, 2015), highlighting the excellent performance of the ceria/zirconia system, however, these systems suffer of serious deactivation, by sintering and coking (Zalc et al., 2002), in real process conditions and a high methane selectivity (Torrente-Murciano et al., 2015). A molybdenum promotion effect was recently reported, for Pt-carbon supported catalysts, increasing the turnover frequency up to a factor of 4000 (Sener et al., 2016); while a comparative study of platinum catalysts supported on M-doped cerium oxide (M = Ca, La, Mg, Zn, Zr, Yb, Y, Gd) have shown a promotion effect on the activity, depending on the nature of the dopant, varying in the order of Yb>Gd>Zr>Mg>La>CeO2(undoped) >Ca>Y>Zn (Panagiotopoulou et al., 2007).	cache/cet-3727.htm	txt/cet-3727.txt
