Abstract

A SO3H-bearing mesoporous carbon material was investigated as a new type of heterogeneous catalyst. Carbonization of resorcinol-formaldehyde resin at 773 K, followed by sulfonation results in amorphous carbon consisting of graphene with high densities of SO3H (0.9 mmol g-1) and phenolic OH (2.0 mmol g-1) groups. The mesoporous carbon that has a large surface area (433 m2 g-1) due to uniform mesopores (ca. 10 nm) exhibits remarkable catalytic performance for the selective dimerization of α-methylstyrene (AMS); the selectivity for unsaturated AMS dimers exceeds 99%. This catalysis is attributed to not only the large surface area based on large mesoporosity, but also to preventing intramolecular Friedel-Crafts alkylation.
