Catalysis and capacitance on nano-structured gold particles and sponges

Abstract

In the present paper we describe the catalytic properties and electrolytic double-layer capacitance of nano-structured, mesoporous gold sponges. These materials are effective catalysts for CO oxidation, and for the selective catalytic conversion of NOx. The possible application of mesoporous gold in electric double layer capacitors is premised on its high surface area, corrosion resistance and excellent electrical conductivity. The niche, if any exists, would be in high-efficiency, and high-power density ultra-capacitors for top-end consumer appliances.
