Breaking the Intrinsic Activity Barriers of Bilayer Metal Oxides for Catalytic Co2 Reduction

The photocatalytic CO2 reduction reaction is severely limited by sluggish charge kinetics. To address this issue, a strategy utilizing non-metal-doped layered double hydroxide (LDH) has been developed to control the electronic structure of spindle-shaped nanoflowers, resulting in efficient photocatalytic CO2 reduction. The results demonstrate that the designed catalyst yields 263.16 mu mol g-1 h-1 for the photoreduction of CO2 to CO. Furthermore, the in situ Fourier transform infrared spectrum (FT-IR) analysis demonstrate that the specific Sligand (S-bridge) facilitates CO2 activation, ensuring the continuous production of *COOH. The hydrothermalassisted ionic liquid method proposed in this study offers guidance for modifying catalysts.
