“…Furthermore, CO production involves a 2e − /2H + process (CO 2 +2H + +2e − →CO+H 2 O, E°′= −0.53 V, vs. NHE, pH=7) in contrast to ethanol and ethylene (12e − /12H + ). In addition, CO is a multipurpose feedstock in numerous industrial applications [3b,6] …”

Dye‐sensitized photocatalytic systems (DSPs) have been extensively investigated for solar‐driven hydrogen (H2) evolution. However, their application in carbon dioxide (CO2) reduction remains limited. Furthermore, current solar‐driven CO2‐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 CO2‐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‐1vs. CAT).
