Electrodeposition and Characterization of Platinum Nanoparticles onto Aminated Carbon Electrodes Using Electrochemical Dissolution of Platinum Counter Electrode

Abstract

Using the electrochemical dissolution phenomenon of platinum counter electrode, we investigated the surface functionalization and characterization of platinum nanoparticles that had been electrodeposited onto aminated carbon electrodes. The electrodeposited platinum functions with nitrogen-atom-containing functional groups introduced by electrolysis in ammonium carbamate solution. The groups can include aromatic amine groups such as aniline. Together, they function as active sites of specific electrocatalytic current, as found from SEM and XPS observations and electrochemical properties.
