TLDR
The results indicate that the cube growth starts from nuclei formed during the first cycle, followed by a layered deposition and partial dissolution of new material in subsequent cycles, and the concentration of Cl– ions in solution controls the cube size, shape, and coverage.Abstract:
The renewable energy-powered conversion of industrially generated CO2 into useful chemicals and fuels is considered a promising technology for the sustainable development of our modern society. The...read more

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.
