Shunt Pt/FeO _x ‑Al₂O₃ Catalysts for SO₂‑Tolerant CO Oxidation.

ABSTRACT: Sulfur, particularly SO₂, remains one of the primary poisons in catalytic systems for treating exhaust gases. Currently, the elimination of CO is still challenging in the presence of SO₂ at low temperatures (<150 °C). Herein, we introduce a strategyshunt catalysisto development of sulfur-tolerant catalysts for CO oxidation. Shunt Pt/FeO _x -Al₂O₃ catalysts were constructed for CO oxidation in the presence of SO₂, in which tiny Pt nanoparticles with sizes of 3-4 nm were uniformly incorporated onto binary nanohybrids composed of amorphous FeO _x and γ-Al₂O₃. By deliberately adjusting the Fe-to-Al ratio to be about 1:10 at the surface region of the FeO _x -Al₂
