Novel catalysts expanding the temperature range for NO selective catalytic reduction by H₂

Artikel i vetenskaplig tidskrift, 2024

Nobel metal (Pt, Pd, Ir) based catalysts are developed to cover a wide working temperature window for exhaust emission control from H2 2 internal combustion engines. A preliminary exploration including measurement of catalytic activities, redox states, and reaction processes is carried out regarding how the functions of the three metals varied with temperature.
