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

Abstract

Herein, 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.
