High aspect ratio rhodium nanostructures for tunable electrocatalytic performance

Abstract

Rh nanoneedles and nanorods have been generated with the help of functional molecules like hexamethylene tetraamine and tridecylamine (1 : 2 in mM scale) as effective capping agents for electrocatalytic studies. A noteworthy negative shift of the onset potential towards the electrooxidation of formic acid compared to that of bulk Rh from cyclic voltammetry along with current densities from current–time transient suggests their potential application as an efficient electrocatalyst for fuel cell.
