Near-infrared-driven carbon dioxide reduction at 850 nm using water as electron and proton source over a directly connected silver vanadate and zinc rhodate Z-scheme photocatalyst.

We report near-infrared-driven carbon dioxide (CO2) reduction over a directly connected silver vanadate and zinc rhodate (Ag2V4O11/ZnRh2O4, molar ratio of 0.7/1.7) Z-scheme photocatalyst under monochromatic irradiation at 850 nm. With water serving as both the electron and proton source, CO2 is reduced to methane and carbon monoxide, whereas water is oxidized to oxygen.
