Abstract To use water as the source of electrons for proton or CO 2 reduction within electrocatalytic devices, catalysts are required facilitating proton‐coupled multi‐electron oxygen evolution reaction (OER, H O→O +4 + e − ). These catalysts, ideally based on cheap and earth abundant metals, have to display high activity at low overpotential good stability selectivity. While numerous examples Co, Mn, Ni were recently reported oxidation, only few using copper, despite promising efficiencies....

Significance Carbon dioxide electroreduction may constitute a key technology in coming years to valorize CO 2 as high value-added chemicals such hydrocarbons and way store intermittent solar energy durably. Based on readily available technologies, systems combining photovoltaic (PV) cell with an electrolyzer (EC) for reduction are likely strategy tackling this challenge. However, low-cost, sustainable, highly efficient PV–EC system has yet be developed. In article, we show that goal can...
