Abstract

Ru (1 wt%)-based catalysts supported on La(x)-Al2O3 (x=0, 1, 5, and 10 mol%) were synthesized and characterized by X-ray diffraction, Brunauer-Emmett-Teller measurement, scanning electron microscopy, scanning transmission electron microscopy, and temperature-programmed reduction. The as-prepared catalytic materials possessed strong metal-to-support interactions (SMSI) between Ru and La(x)-Al2O3. The Ladoped catalysts were excellent for the dehydrogenation of ammonia; among them, the Ru (1wt%)/La(10)-Al2O3 catalyst exhibited superior performance and improved thermal stability with nearly 100% conversion of ammonia at 650 °C. The incorporated element La is thought to play an important role in enhancing SMSIs, ultimately facilitating ammonia dehydrogenation even at low temperatures.
