TL;DR: In this article, the authors review recent advances and challenges in the understanding of electrochemical CO2 reduction and discuss existing models for the initial activation of CO2 on the electrocatalyst and their importance for understanding selectivity.

TL;DR: A hydrogenated dimer intermediate (OCCOH) is detected using Fourier transform infrared spectroscopy at low overpotentials in LiOH solutions and is structure sensitive, as it is observed only during CO reduction on Cu(100) and not onCu(111), in agreement with previous experimental and computational observations.

TL;DR: Investigation of electrocatalytic reduction of CO to CH4 and C2H4 on copper electrodes in 0.1 M alkaline hydroxide electrolytes found potential-dependent, structure-sensitive cation effects help steer the selectivity toward specific products.

TL;DR: In this article, Nitrate reduction on Cu (100 and Cu (111) surfaces in alkaline and acidic solutions was studied by electrochemical methods coupled with online and in situ characterization techniques (mass spectrometry, ion chromatography and Fourier transformed infra-red spectroscopy) to evaluate the reaction mechanism and products on the different surfaces.

TL;DR: The use of the natural amino acid l-proline as a protecting ligand for ruthenium-based PACT compounds is investigated in a series of complexes and the role of the solvent polarity and coordination properties on the photochemical properties of polypyridyl complexes is discussed.
