Zeolite-promoted platinum catalyst for efficient reduction of nitrogen oxides with hydrogen.

ABSTRACT: Internal combustion engine fueled by carbon-free hydrogen (H₂-ICE) offers a promising alternative for sustainable transportation. Herein, we report a facile and universal strategy through the physical mixing of Pt catalyst with zeolites to significantly improve the catalytic performance in the selective catalytic reduction of nitrogen oxides (NO_x) with H₂ (H₂-SCR), a process aiming at NO_x removal from H₂-ICE. Via the physical mixing of Pt/TiO₂ with Y zeolite (Pt/TiO₂ + Y), a remarkable enhancement of NO_x reduction activity and N₂ selectivity was simultaneously achieved. The incorporation of Y zeolite effectively captured the in-situ generated water, fostering a water-rich environme
