Synthesis and electrochemical double layer characterization of nanoporous gold

The present article highlights synthesis and electrochemical double layer characterisation of nanoporous Au. The electrochemical double layer studies were carried out on nanoporous Au samples immersed in a weakly adsorbing HClO4 electrolyte in-situ in three-electrode cell geometry. The specific-volumetric capacitance value obtained from the double layer charging experiments are discussed in terms of the variation in ligament diameter.
