Synergistic Dual Sites in a Cobalt‑Porphyrin Polymer Enable Tunable Syngas Production from CO2 Photoreduction

Key Points

• This research aims to investigate the efficiency of cobalt-porphyrin polymers in converting CO2 to syngas under visible light.
• Utilized a cobalt-porphyrin organic polymer (CoBpyPOP) with dual active sites for CO2 photoreduction.
• Assessed syngas production rates under visible light exposure.
• Achieved a syngas production rate of 9.8, indicating high efficiency in CO2 conversion.
• Demonstrated effective performance of both active sites (CoN4 and CoN2Cl2) in the conversion process.
