Catalytic Oxidation of Propane and Carbon Monoxide by Pd Nanoparticles on Mn/TiO2 Catalysts

Abstract The present work shows experimental results on the catalytic oxidation of C 3 H 8 and CO by Pd nanoparticles supported MnO x /TiO 2 synthesized sol–gel method. show a strong interaction between ; likewise, annealing temperature TiO support modified properties Pd–MnO catalyst. In this line, catalysts with 1 wt% loading showed outstanding activity oxidizing within two intervals: 200–400 °C 25–200 °C, respectively. catalyst also displayed very high stability during long-term tests addition reduced greatly . outcomes revealed that Pd–Mn promoted formation new 0 /Pd 2+ active sites as well oxygen vacancies Ti 4+ to 3+ species, which led improvement Mn redox features, thus boosting capacity Graphical
