Abstract：Carbon nanotubes (CNTs) and graphene were separately incorporated into the cross-linked network of styrene-divinylbenzene composites via in situ suspension polymerization. The prepared ion exchange resin composite catalysts exhibited remarkable enhancement in total ion exchange capacities, anti-swelling properties and thermal stabilities with strong interaction within the polymer networks. It showed that the addition of graphene to the polymer matrix greatly increased the onset degradation temperature by 15 ℃. The heterogeneous catalytic hydration to ethylene glycol confirmed that graphene-based composite catalysts showed better catalytic performance in activity and selectivity. With the excellent anti-swelling property and thermal stability, graphene-based composite catalysts exhibited enhanced reaction stability with ethylene glycol yield of 95% during 300 h experiment.
