Immobilization on a structured substrate is a prerequisite for exploiting practical applications for graphene as a catalytic support. Here we report that graphene oxide (GO) nanosheets can readily form a stable coating on a cordierite honeycomb substrate without any need of stabilizers. FT-IR and1H NMR characterization revealed that GO nanosheets were probably immobilized on the cordierite surface by hydrogen bonding. TEM analysis indicated that palladium particles loaded on the graphene/cordierite exhibited a uniform size of less than 5 nm, which led to 4 times higher activity for styrene hydrogenation than that loaded on the cordierite.
