Abstract:
Dye‐sensitized photocatalytic systems (DSPs) have been extensively investigated for solar‐driven hydrogen (H 2 ) evolution. However, their application in carbon dioxide (CO 2 ) reduction remains limited. Furthermore, current solar‐driven CO 2 ‐to‐CO DSPs typically employ rhenium complexes as catalysts. In this study, we have developed DSPs that incorporate noble metal‐free components, specifically a zinc‐porphyrin as photosensitizer (PS) and a cobalt‐quaterpyridine as catalyst (CAT). Taking a significant stride forward, we have achieved an antenna effect for the first time in CO 2 ‐to‐CO DSPs by introducing a Bodipy as an additional chromophore to enhance light harvesting efficiency. The energy transfer from Bodipy to zinc porphyrin resulted in remarkable stability (turn over number (TON)=759 vs. CAT), and high CO evolution activity (42 mmol g −1 h −1 vs. CAT).
