We report the synthesis of graphene-mesoporous silica nanoparticle (MSN) hybrids by selective growth of the latter on graphene oxide sheets using a cationic surfactant-templated method. The MSNs were just a few tens of nanometers in size, exhibited internal mesopores ∼3.7-4 nm wide and appeared to be firmly attached to the graphene sheets. The nanoparticles could also be produced with varying densities on the graphene support, from isolated entities up to close-packed monolayers uniformly coating both sides of the sheets, which allowed fine-tuning the porous texture of the materials on the basis of their interparticle porosity. The experimental conditions that afford the generation of these graphene-MSN hybrids are also discussed.
