Regulating coordination number in atomically dispersed Pt species on defect-rich graphene for n-butane dehydrogenation reaction.

ABSTRACT: Metal nanoparticle (NP), cluster and isolated metal atom (or single atom, SA) exhibit different catalytic performance in heterogeneous catalysis originating from their distinct nanostructures. To maximize atom efficiency and boost activity for catalysis, the construction of structure-performance relationship provides an effective way at the atomic level. Here, we successfully fabricate fully exposed Pt₃ clusters on the defective nanodiamond@graphene (ND@G) by the assistance of atomically dispersed Sn promoters, and correlated the n-butane direct dehydrogenation (DDH) activity with the average coordination number (CN) of Pt-Pt bond in Pt NP, Pt₃ cluster and Pt SA for fundamentally understanding structure (especially the sub-nano structure) effects on n-butane DDH react
