Abstract

Abstract : Low-coordinated surface atoms of nanoporous gold are responsible for high performance electrochemical CO2 reduction to CO. Abstract : First principles calculations show that gold atoms with low generalized coordination numbers possess high activity for electroreduction of CO2 to CO. Atom-resolved three-dimensional reconstruction reveals that dealloyed nanoporous gold possesses such a favourable structure characteristic, which results in a faradaic efficiency as high as 94% for CO production.
