Light-driven biohybrid system utilizes N₂ for photochemical CO₂ reduction.

ABSTRACT: Attempting to couple photochemical CO₂ reduction with N₂ fixation is usually difficult, because the reaction conditions for these two processes are typically incompatible. Here, we report that a light-driven biohybrid system can utilize abundant, atmospheric N₂ to produce electron donors via biological nitrogen fixation, to achieve effective photochemical CO₂ reduction. This biohybrid system is constructed by incorporating molecular cobalt-based photocatalysts into N₂-fixing bacteria. It is found that N₂-fixing bacteria can convert N₂ into reductive organic nitrogen and create a localized anaerobic environment, which allows the incorporated photocatalysts to continuously perform photocatalytic CO₂ reduc
