Abstract

In this perspective we compare plasmon-enhanced electrochemical conversion (PEEC) with photoelectrochemistry (PEC). PEEC is the oxidation or reduction of a reactant at the illuminated surface of a plasmonic metal (or other conductive material) while a potential bias is applied. PEC uses solar light to generate photoexcited electron-hole pairs to drive an electrochemical reaction at a biased or unbiased semiconductor photoelectrode. The mechanism of photoexcitation of charge carriers is different between PEEC and PEC. Here we explore how this difference affects the response of PEEC and PEC systems to changes in light, temperature, and surface morphology of the photoelectrode.

In Situ ATR–SEIRAS of Carbon Dioxide Reduction at a Plasmonic Silver Cathode

Journal Article Corson, Elizabeth R. ; Kas, Recep ; Kostecki, Robert ; ... - Journal of the American Chemical Society

Illumination of a voltage-biased plasmonic Ag cathode during CO₂ reduction results in a suppression of the H₂ evolution reaction while enhancing CO₂ reduction. This effect has been shown to be photonic rather than thermal, but the exact plasmonic mechanism is unknown. Here in this paper, we conduct an in situ ATR–SEIRAS (attenuated total reflectance–surface-enhanced infrared absorption spectroscopy) study of a sputtered thin film Ag cathode on a Ge ATR crystal in CO₂-saturated 0.1 M KHCO₃ over a range of potentials under both dark and illuminated (365 nm, 125 mW cm^–2) conditions to elucidate the nature of this plasmonic enhancement.

Directing Selectivity of Electrochemical Carbon Dioxide Reduction Using Plasmonics

Journal Article Creel, Erin B. ; Corson, Elizabeth R. ; Eichhorn, Johanna ; ... - ACS Energy Letters

Catalysts for electrochemical carbon dioxide reduction in aqueous electrolytes suffer from high energy input requirements, competition with hydrogen evolution from water reduction, and low product selectivity. Theory suggests that plasmonic catalysts can be tuned to selectively lower the energy barrier for a specific reaction in a set of competitive reactions, but there has been little experimental evidence demonstrating plasmon-driven selectivity in complicated multielectron electrochemical processes. Here, the photoactivity at a plasmonically active silver thin film electrode at small cathodic potentials selectively generates carbon monoxide while simultaneously suppressing hydrogen production. At larger cathodic potentials, the photoactivity promotes production of methanol andmore »« less

Reduction of carbon dioxide at a plasmonically active copper–silver cathode

Journal Article Corson, Elizabeth R. ; Subramani, Ananya ; Cooper, Jason K. ; ... - ChemComm

Electrochemically deposited copper nanostructures were coated with silver to create a plasmonically active cathode for carbon dioxide (CO₂) reduction. Illumination with 365 nm light, close to the peak plasmon resonance of silver, selectively enhanced 5 of the 14 typically observed copper CO₂ reduction products while simultaneously suppressing hydrogen evolution. At low overpotentials, carbon monoxide was promoted in the light and at high overpotentials ethylene, methane, formate, and allyl alcohol were enhanced upon illumination; generally C₁ products and C₂/C₃ products containing a double carbon bond were selectively promoted under illumination. Temperature-dependent product analysis in the dark showed that local heating ismore »« less

Surface-Plasmon-Assisted Photoelectrochemical Reduction of CO₂ and NO₃^– on Nanostructured Silver Electrodes

Journal Article Kim, Youngsang ; Creel, Erin B. ; Corson, Elizabeth R. ; ... - Advanced Energy Materials

Electrochemical reduction of carbon dioxide (CO₂) typically suffers from low selectivity and poor reaction rates that necessitate high overpotentials, which impede its possible application for CO₂ capture, sequestration, or carbon-based fuel production. New strategies to address these issues include the utilization of photoexcited charge carriers to overcome activation barriers for reactions that produce desirable products. Here, this study demonstrates surface-plasmon-enhanced photoelectrochemical reduction of CO₂ and nitrate (NO₃^-) on silver nanostructured electrodes. The observed photocurrent likely originates from a resonant charge transfer between the photogenerated plasmonic hot electrons and the lowest unoccupied molecular orbital (MO) acceptor energy levels of adsorbed CO₂,more »« less

Long-term stability studies of a semiconductor photoelectrode in three-electrode configuration

Journal Article Vanka, Srinivas ; Sun, Kai ; Zeng, Guosong ; ... - Journal of Materials Chemistry. A

Improving the stability of semiconductor materials is one of the major challenges for sustainable and economic photoelectrochemical water splitting. N-terminated GaN nanostructures have emerged as a practical protective layer for conventional high efficiency but unstable Si and III–V photoelectrodes due to their near-perfect conduction band-alignment, which enables efficient extraction of photo-generated electrons, and N-terminated surfaces, which protects against chemical and photo-corrosion. In this paper, we demonstrate that Pt-decorated GaN nanostructures on an n⁺–p Si photocathode can exhibit an ultrahigh stability of 3000 h (i.e., over 500 days for usable sunlight ~5.5 h per day) at a large photocurrent density (>35more »« less
