摘要：

A one step polyol process has been used to synthesize linear assemblies of Pd nanoparticles (NPs). TEM images show that highly linearly ordered Pd NP chains (about 8.5 nm in diameter) have been formed, and the inter-particle distance is about 1.4 +/- 0.6 nm. The Pd NP chains can be obtained by adding NH3 center dot H2O and prolonging the heating time. A scaffolding mechanism is proposed to understand the short-ranged order of the Pd NP chains. The as-obtained Pd nanochains at Pd NCh/MWCNTs/GCE displayed high activity in the electrocatalytic oxidation of NO. (C) 2008 Elsevier Masson SAS. All rights reserved.
