Key Points

This study aims to enhance the performance of Pd-based catalysts for NOx removal in H2 engines under high water concentrations.
Employed Pd-based catalysts on oxide supports (TiO2 and ZrO2)
Conducted experiments to assess catalytic performance in high water concentrations
Evaluated water resistance of the catalysts
Pd catalysts showed improved NOx removal efficiency with oxide supports
Demonstrated effective performance despite high water concentrations
Improved resilience against water poisoning compared to traditional approaches

Implication

Investigates NOx removal efficiency in H2 engines, suggesting improved catalytic performance.

Abstract

The two main challenges of application of Pd-based catalysts in H2-SCR are catalytic performance and water resistance. In this study, oxide supports (TiO2 and ZrO2) were employed and experimentally demonstrated...
