Abstract

Electroless synthesis and hierarchical organization of 1.4 nm Pd and Ptnanoparticles (NPs) on self-assembled Rosette Nanotubes (RNTs) is described.The nucleated NPs are nearly monodisperse and reveal supramolecularorganizations guided by RNT templates. Interestingly, the narrow sizedistribution is attributable to unique templating behavior of RNTs. Theresulting metal NP-RNT composites were characterized by Atomic ForceMicroscopy (AFM), Scanning Electron Microscopy (SEM) and TransmissionElectron Microscopy (TEM). X-ray Photoelectron Spectroscopy (XPS) was alsoperformed to confirm the nature and composition of RNT-templated NPs.
