Visible-Light-Induced Selective CO₂ Reduction Utilizing a Ruthenium Complex Electrocatalyst Linked to a p-Type Nitrogen-Doped Ta₂O₅ Semiconductor

Lights, CO2, action! Selective CO2 reduction by hybrid photocatalysts such as a p‐type semiconductor and a ruthenium complex catalyst (see picture) was induced by visible light. The quantum efficiency for HCOOH production was 1.9 % at 405 nm. For electron transfer, it is essential that the potential...

Description
Summary:Lights, CO2, action! Selective CO2 reduction by hybrid photocatalysts such as a p‐type semiconductor and a ruthenium complex catalyst (see picture) was induced by visible light. The quantum efficiency for HCOOH production was 1.9 % at 405 nm. For electron transfer, it is essential that the potential of the conduction band minimum of the semiconductor is more negative than the reduction potential of the complex catalyst.
