a–c Pre-exponential factors (a), apparent activation energies (b) and turnover rates (c) over Cu/LTA, Cu/AEI, Cu/CHA-a, and Cu/CHA-b. Error bars in (b) represent standard deviation of linear regression in Arrhenius analysis. The reactant feed contains 350 ppm NOx (including ∼10 ppm NO2), 350 ppm NH3, 2.5% H2O, 10% O2, and balanced N2 at a gas hourly space velocity (GHSV) of ∼2 × 105 h−1.
