Abstract
An apparatus and method for COreduction using an Auelectrode. The Auelectrode is comprised of ligand-protected Auhaving a structure comprising an icosahedral core of 13 atoms surrounded by a shell of six semi-ring structures bonded to the core of 13 atoms, where each semi-ring structure is typically —SR—Au—SR—Au—SR or —SeR—Au—SeR—Au—SeR. The 12 semi-ring gold atoms within the six semi-ring structures are stellated on 12 of the 20 faces of the icosahedron of the Aucore, and organic ligand —SR or —SeR groups are bonded to the Aucore with sulfur or selenium atoms. The Auelectrode and a counter-electrode are in contact with an electrolyte comprising COand H+, and a potential of at least −0.1 volts is applied from the Auelectrode to the counter-electrode.
