Journal ArticleDOI
CO2 Reduction at Low Overpotential on Cu Electrodes Resulting from the Reduction of Thick Cu2O Films
Christina W. Li,Matthew W. Kanan +1 more
TL;DR: Modified Cu electrodes were prepared by annealing Cu foil in air and electrochemically reducing the resulting Cu(2)O layers, which resulted in electrodes whose activities were indistinguishable from those of polycrystalline Cu and a higher level of activity than all previously reported metal electrodes evaluated under comparable conditions.
Journal ArticleDOI
Aqueous CO2 reduction at very low overpotential on oxide-derived Au nanoparticles.
TL;DR: Electrokinetic studies indicate that the improved catalysis is linked to dramatically increased stabilization of the CO(2)(•-) intermediate on the surfaces of the oxide-derived Au electrodes.
Journal ArticleDOI
Electroreduction of carbon monoxide to liquid fuel on oxide-derived nanocrystalline copper
TL;DR: The results demonstrate the ability to change the intrinsic catalytic properties of Cu for this notoriously difficult reaction by growing interconnected nanocrystallites from the constrained environment of an oxide lattice, demonstrating the feasibility of a two-step conversion of CO2 to liquid fuel that could be powered by renewable electricity.
Journal ArticleDOI
Probing the Active Surface Sites for CO Reduction on Oxide-Derived Copper Electrocatalysts
Arnau Verdaguer-Casadevall,Christina W. Li,Tobias Peter Johansson,Søren Bertelsen Scott,Joseph T. McKeown,Mukul Kumar,Ifan E. L. Stephens,Matthew W. Kanan,Ib Chorkendorff +8 more
TL;DR: It is proposed that the active sites for CO reduction on OD-Cu surfaces are strong CO binding sites that are supported by grain boundaries that are distinct from the terraces and stepped sites found on polycrystalline Cu foil.
Journal ArticleDOI
Finite-Size Effects in O and CO Adsorption for the Late Transition Metals
Andrew A. Peterson,Lars C. Grabow,Thomas P. Brennan,Bonggeun Shong,Chin Chun Ooi,Di Wu,Christina W. Li,Amit Kushwaha,Andrew J. Medford,Felix Mbuga,Lin Li,Jens K. Nørskov,Jens K. Nørskov +12 more
TL;DR: In this article, the authors used density functional theory to study adsorption of representative adsorbates, CO and O, on the late transition metals Co, Ni, Cu, Ir, Pd, Ag, Rh, Pt and Au.
