Liquid-Phase Ethanol Oxidation and Gas-Phase CO Oxidation Reactions over M Doped (M = Ag, Au, Pd, and Ni) and MM′ Codoped CeO2 Nanoparticles

Figure 6

1st (a) and 2nd (b) run temperature programmed CO oxidation conversion (%) profiles (a, b) of undoped CeO2 and Au and Ag doped and codoped (5/0, 0/5, 4/1, 2.5/2.5, and 1/4 mol.%) CeO2 catalysts. The difference (c) in T10% between the metal doped and bare CeO2 for the 1st and 2nd runs. The difference (d) in T10% between the 1st and 2nd runs for the metal doped CeO2 catalysts. Optical microscope images showed the color of the powder samples before and after CO oxidation reactions.
