a NOx conversion, and (b) N2 selectivity in H2-SCR reaction; c NO selective conversion (i.e., NO reacting with H2 or O2) in H2-SCR reaction over Pt/TiO2 and Pt/TiO2 + Y catalysts (see Methods section for detailed calculation); d Correlation between N2 selectivity and NOx conversion in H2-SCR reaction over Pt/TiO2, Pt/TiO2 + TiO2, and Pt/TiO2 + Y catalysts. Reaction conditions: 26 mg of Pt/TiO2 catalyst, or a physical mixture containing 26 mg of Pt/TiO2 and 26 mg of Y or TiO2; steady-state testing; 500 ppm NO, 1% H2, 10% O2, 5% CO2, and 5% H2O; weight hourly space velocity (WHSV) = 461,540 mL·gPt/TiO2–1·h–1.
