摘要

This study proposes a novel hybrid framework that integrates amine-functionalized biochar panels with photovoltaic (PV)-assisted airflow and microbial fuel cells (MFCs) for simultaneous carbon capture and renewable energy generation. The system incorporates real-time electrochemical sensors for adaptive optimization, enabling efficient and scalable deployment. Performance was evaluated using NOAA Mauna Loa CO₂ data (post-July 2023) and validated through system-level simulations. Results show a CO₂ adsorption capacity of 3–4 mmol/g with an overall capture efficiency of 85%, while PV integration delivers a net energy output of 175 W/m2. The framework achieved a sustainability score of 74.5%, highlighting its potential as a climate-neutral and energy-positive carbon management solution.
