Ordered mesoporous Mn₂O₃ (meso-Mn₂O₃) and meso-Mn₂O₃-supported Pd, Pt, and Pd-Pt alloy x(Pd_yPt)/meso-Mn₂O₃; x=(0.10-1.50) wt%; Pd/Pt molar ratio (y)=4.9-5.1 nanocatalysts were prepared using KIT-6-templated and poly(vinyl alcohol)-protected reduction methods, respectively. The meso-Mn₂O₃ had a high surface area, i.e., 106 m²/g, and a cubic crystal structure. Noble-metal nanoparticles (NPs) of size 2.1-2.8 nm were uniformly dispersed on the meso-Mn₂O₃ surfaces. Al-loying Pd with Pt enhanced the catalytic activity in methane combustion; 1.41(Pd_5.1Pt)/meso-Mn₂O₃ gave the best performance; T_10%, T_50%, and T_90% (the temperatures required for achieving methane conversions of 10%, 50%, and 90%) were 265, 345, and 425℃, respectively, at a space velocity of 20000 mL/(g·h). The effects of SO₂, CO₂, H₂O, and NO on methane combustion over 1.41(Pd_5.1Pt)/meso-Mn₂O₃ were also examined. We conclude that the good catalytic performance of 1.41(Pd_5.1Pt)/meso-Mn₂O₃ is associated with its high-quality porous structure, high adsorbed oxy-gen species concentration, good low-temperature reducibility, and strong interactions between Pd-Pt alloy NPs and the meso-Mn₂O₃ support.
