Solar-driven conversion of CO₂ and H₂O into chemicals is a promising strategy, yet achieving simultaneous and efficient CO₂ reduction and H₂O oxidation remains challenging. Here, the authors design silver-modified tungsten trioxide that acts as a charge reservoir via reversible W⁶⁺/W⁵⁺ transitions under irradiation, enabling efficient CO₂ photoreduction with H₂O.

Electrochemical CO2 reduction in acidic media offers a promising route for CO2 valorization but faces challenges owing to competing hydrogen evolution and sluggish C–C coupling. Here the authors demonstrate that surface-adsorbed iodide ions enhance performance on Cu-based catalysts, doubling ethylene selectivity and reducing overpotentials.
