چکیده

We demonstrate the synthesis of 2D metal nanoparticles (MNPs)/graphene nanocomposites using small cationic surfactants as stabilizers. 2D sandwich-like MNPs/graphene nanocomposites with a uniform distribution of MNPs can be achieved via a one-pot in situ growth and reduction protocol.

Direct synthesis of noble metal/graphene nanocomposites from graphite in water: photo-synthesis.

We report on the direct and facile method for noble metal/graphene nano-composites from graphite without reducing agents. In this system, the irradiant white-light instead of the chemical reducing agent exerts the influence on the synthesis of noble metal nanoparticles on graphene. Noble metal salts adsorbed on graphene flakes which were functionalized with ionic surfactants were reduced by irr...

Synthesis of graphene based noble metal composites for glucose biosensor

Graphene (GR) based noble metal composites such as Pt–GR and Au–GR were synthesized for sensitive glucose biosensors. Aerosol spray pyrolysis (ASP) was employed to synthesize the noble metal nanoparticles–GR composites using a colloidal mixture of GO and noble metal precursor (H2PtCl6 6H2O and AuCl4 3H2O). The morphology of noble metal–GR composites was generally the shape of a crumpled paper b...

Highly stable mesoporous metal oxides using nano-propping hybrid gemini surfactants.

Noble Gemini surfactants containing a siloxane moiety have been designed and successfully synthesized in the present study and are utilized as structure-directing agents for mesoporous metal oxides such as zirconia, titania, and vanadia. The siloxane moiety is believed to play an important nano-propping role during the surfactant removal by direct calcination, yielding thermally stable mesoporo...
