Abstract
- Abstract: Pt nanoparticles (NPs) immobilized on a core–shell hybrid carbon support allow the efficient direct dehydrogenation of <italic>n</italic>‐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 (≈25 % conversion with >95 % selectivity toward olefins) at 450 °C for over 10 h as a result of strong metal–support interactions. The catalyst can also be fully regenerated by postoxidative thermal treatment. [ABSTRACT FROM AUTHOR]
