Carbon dioxide reduction reactions, a key step in creating fuels from this gas, can be achieved in an ionic liquid. Electroreduction of carbon dioxide (CO2)—a key component of artificial photosynthesis—has largely been stymied by the impractically high overpotentials necessary to drive the process. We report an electrocatalytic system that reduces CO2 to carbon monoxide (CO) at overpotentials below 0.2 volt. The system relies on an ionic liquid electrolyte to lower the energy of the (CO2… 
Selective conversion of CO2 to CO with high efficiency using an inexpensive bismuth-based electrocatalyst.
An inexpensive bismuth-carbon monoxide evolving catalyst that can be formed upon cathodic polarization of an inert glassy carbon electrode in acidic solutions containing Bi(3+) ions is reported, which correspond to a high-energy efficiency for CO production, on par with that which has historically only been observed using expensive silver and gold cathodes.
Electrochemical carbon dioxide reduction in ionic liquids at high pressure.
This work explores the electrochemical reduction of CO2 at high pressures and demonstrates a correlation between the volume of expansion of the ionic liquid and the achieved catalytic current density, a step towards realising an integrated CO2 capture and utilisation system based around a common ionicLiquid.
Efficient Photoelectrochemical Reduction of Carbon Dioxide to Formic Acid: A Functionalized Ionic Liquid as an Absorbent and Electrolyte.
A new concept is proposed in which a PEC system is used to capture and convert CO2 into formic acid, assisted by an ionic liquid aqueous solution, which functions as an absorbent and electrolyte at ambient temperature and pressure.
Reduction of Carbon Dioxide to Formate at Low Overpotential Using a Superbase Ionic Liquid
A new low-energy pathway is reported for the electrochemical reduction of CO2 to formate and syngas at low overpotentials, utilizing a reactive ionic liquid as the solvent. The superbasic tetraalkyl
Insights into the Low Overpotential Electroreduction of CO2 to CO on a Supported Gold Catalyst in an Alkaline Flow Electrolyzer
Cost competitive electroreduction of CO2 to CO requires electrochemical systems that exhibit partial current density (jCO) exceeding 150 mA cm–2 at cell overpotentials (|ηcell|) less than 1 V.
Molecular tuning of CO2-to-ethylene conversion
Electrocatalytic reduction of CO2 over copper can be made highly selective by ‘tuning’ the copper surface with adsorbed organic molecules to stabilize intermediates for carbon-based fuels such as ethylene.
High Performance Fe Porphyrin/Ionic Liquid Co-catalyst for Electrochemical CO2 Reduction.
This work shows that the addition of an ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate, in an aprotic electrolyte containing a proton source and FeTPP promotes the in situ formation of the [Fe(0) TPP](2-) homogeneous catalyst at a less negative potential, resulting in lower overpotentials for the CO2 reduction and increased kinetics of electron transfer.
Ionic Liquid Co-catalyzed Artificial Photosynthesis of CO
The conversion of CO2 to chemical feedstocks is of great importance, which yet requires the activation of thermodynamically-stable CO2 by metal catalysts or metalloenzymes. Recently, the development
Electrolytic CO2 Reduction in a Flow Cell.
This Account examines some of the systems-level strategies that have been applied in an effort to tailor flow reactor components to improve electrocatalytic reduction and highlights the challenges associated with precise and controlled water management in gas phase CO2 electrolyzers.


Development of molecular electrocatalysts for CO2 reduction and H2 production/oxidation.
Progress is described in the development of redox-active carriers capable of concentrating CO(2) and molecular electrocatalysts for CO( 2) reduction, hydrogen production, and hydrogen oxidation, and much more remains to be done.
Electrocatalytic carbon dioxide activation: the rate-determining step of pyridinium-catalyzed CO2 reduction.
Concentration experiments show that the catalytic current measured by cyclic voltammetry increases linearly with pyridinium and CO(2) concentrations; this indicates that the rate-determining step is first order in both.
Using a one-electron shuttle for the multielectron reduction of CO2 to methanol: kinetic, mechanistic, and structural insights.
Evidence for the mechanism of the reduction proceeding through various coordinative interactions between the pyridinium radical and carbon dioxide, formaldehyde, and related species is shown, which suggests an inner-sphere-type electron transfer from the pyrsid inium radical to the substrate for various mechanistic steps where the p Pyridinia radical covalently binds to intermediates and radical species.
