Synthesis of bifunctional Ru–Pd catalysts following a double reduction method: hydrogenation/dehydrogenation of liquid organic hydrogen carriers

Treatment of Ru 2.5 Pd 2.5 /H 2 catalyst with Ar–H 2 mixture exposed strong acid sites, prompting further reduction of Ru n + and Pd 2+ , leading to enhanced interaction of Ru and Pd with carrier, possessing excellent hydrogenation–dehydrogenation activity.
