A synergistic photothermal-dual site strategy to accelerate proton–electron transfer enables enhanced CO 2 -to-syngas conversion

This work demonstrates a synergistic photothermal-dual-site strategy that simultaneously accelerates CO 2 reduction and H 2 O oxidation to maximize proton–electron transfer, achieving an exceptional syngas productivity of 1.97 mmol g⁻¹ h⁻¹.
