Shape-controlled synthesis of metal nanocrystals–multiwalled carbon nanotubes hybrid structures via electrodeposition

Abstract

We have exploited a method for the synthesis of metal nanocrystals (NCs) with distinct geometries on multiwalled carbon nanotubes (MWCNTs) by employing the electrodeposition technique at room-temperature. The method has been demonstrated for the Cu NCs–MWCNTs hybrid structures. The shape of the Cu NCs on MWCNTs has been effectively manipulated by simply tuning the applied potential. The present work provides an alternative approach for the large scale synthesis of shape-controlled metal or/and alloy NCs–MWCNTs hybrid structures for a wide range of applications.
