Capping induced morphology evolution of Rh nanostructures and their electrocatalytic studies

A simple and versatile route based on a galvanic displacement approach for the shape-selective evolution of Rh nanostructures followed by their in situ integration assembly on a large scale has been designed and successfully developed by using polyvinylpyrrolidone (PVP) as a shape inducing agent. Comparative studies on the electrocatalytic activity of these morphologies were conducted towards many fuel cell reactions as demonstrated by HCHO oxidation.
