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.
