An Electrochemical Reduction Cell Model of Photosynthesis forCarbon Dioxide Capture

Abstract

This study presents an electrochemical reduction cell model for photosynthesis aimed at enhancing carbon dioxide capture. Utilizing Simulink, we simulated a system where varying current supplies were applied to assess the production of formic acid and the consumption of carbon dioxide over time. The model demonstrated a direct correlation between current supply and the rates of formic acid generation and CO2 consumption, with significant increases observed at higher current levels. Initial measurements indicated a formic acid production rate of approximately 0.000492 moles/s at 0.1 A, which increased substantially to 0.002217 moles/s at 0.450 A. Concurrently, CO2 consumption escalated from zero to over 36.42 moles/s, underscoring the efficacy of the electrochemical process. The results highlight the potential of electrochemical reduction cells in mitigating atmospheric CO2 levels
while producing valuable chemicals, thereby contributing to advancements in sustainable energy and environmental management. Further investigations will focus on optimizing operational parameters to maximize efficiency and scalability for practical applications.
