Abstract: Pt/La-Ba-Al2O3 and Pt/La-Ba-Al2O3/H-ZSM-5 catalysts showed high N2 selectivity (SN2) from 106 to 506 篊 in treating the exhaust from hydrogen-powered vehicles. SN2 increased with increasing temperature, and SN2 over Pt/La-Ba-Al2O3/H-ZSM-5 was higher than that over Pt/La-Ba-Al2O3. The Pt/La-Ba-Al2O3/H-ZSM-5 catalyst gave enhanced SN2.
