The Cu2+ reduction and H2 evolution on the hetero-system CuFeO2/ZnO under visible light
Applied Water Science, 2020 The hetero-system CuFeO2/ZnO was successfully used in the Cu2+ reduction under visible light irradiation; it was conducted with varying some important factors such as the initial Cu2+ concentration, mass ratio CuFeO2/ZnO and light flux.

Advanced Functional Materials, EarlyView.A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)
