摘要Pt nanoparticles (NPs) immobilized on a core-shell hybrid carbon support allow the efficient direct dehydrogenation of n-butane at low temperatures. The hybrid carbon support is composed of a nanodiamond core and a reinforced ultrathin graphene shell (ND@G), which improves the stability of the anchored Pt NPs against sintering under the reaction conditions. The as-prepared Pt/ND@G catalyst demonstrates excellent catalytic performance (approximate to 25% conversion with > 95% selectivity toward olefins) at 450 degrees C for over 10h as a result of strong metal-support interactions. The catalyst can also be fully regenerated by postoxidative thermal treatment.; Pt nanoparticles (NPs) immobilized on a core-shell hybrid carbon support allow the efficient direct dehydrogenation of n-butane at low temperatures.
