▎ 摘　　要

A noble Pt nanoworms (PtNWs)/p-aminothiophenol (pATP-beta-cyclodextrin polymer (beta-CDP)/reduced graphene oxide (PtNWs/pATP-beta-CDP/rGO) nanocomposite is synthesized using the self-assembly strategy. Inclusion complexes between beta-CDP and pATP are modified onto the surface of rGO through non-covalent bond force. Then, pre-prepared PtNWs self-assemble onto the surface of pATP-beta-CDP/rGO through thiol and amino groups of pATP to fabricate PtNWs/pATP-beta-CDP/rGO hybrid materials. It is verified that the PtNWs may be uniformly scattered on rGO and the amount of PtNWs may be adjusted changing the weight ratio of pATP-beta-CDP:rGO. Cyclic voltammograms show that the PtNW5/pATP-beta-CDP/ rGO catalysts have higher active surface area, more improved performance and better stability towards the electrocatalytic oxidation of methanol than commercial Pt/C catalysts. The proposed synthesis strategy provides a moderate, feasible and effective method for developing noble metals electrocatalysts for methanol oxidation reaction. (C) 2014 Published by Elsevier B.V.
