Low-Temperature Standard-SCR over Cu-SSZ-13: Selective Inhibition of the Oxidation Half-Cycle by Mild Hydrothermal Aging

Key Points

• To explore the effects of mild hydrothermal aging on the reduction and oxidation half-cycles in low-temperature standard-SCR.
• Conducted transient response methods and transient kinetic analysis.
• Tested conditions in the temperature range of 150-200 °C.
• Decoupled the reduction and oxidation half-cycles for analysis.
• Mild hydrothermal aging selectively inhibited the oxidation half-cycle.
• The reduction half-cycle remained unaffected under the same conditions.
