Highly dispersed buckybowls as model carbocatalysts for C–H bond activation

Abstract

Fullerene-derived buckybowl fractions dispersed on mesoporous silica constitute an ideal model for studying the catalysis of graphitic forms of carbon since the dispersed carbon nanostructures contain a high ratio of edge defects and curvature induced by non-six-membered rings. Dispersion of the active centers on an easily accessible high surface area material allowed for high density of surface active sites associated with oxygenated structures. This report illustrates a facile method of creating model polycyclic aromatic nano-structures that are not only active for alkane C–H bond activation and oxidative dehydrogenation but also can be practical catalysts to be eventually used in industry.
