In situ self-assembly of amine-rich carbon supraparticles for rapid CO 2 capture

Key Points

• This research aims to enhance CO2 capture efficiency using amine-rich carbon supraparticles through in situ self-assembly.
• In situ self-assembly technique was used to graft amines onto carbon supraparticles.
• Assessment of CO2 uptake capacity and amine efficiency in different configurations.
• Comparison of results with standard post-loading methods.
• Achieved a 2.4-fold higher CO2 capture capacity of 2.87 mmol g−1.
• Demonstrated 49% amine efficiency, compared to 22% for traditional post-loading methods.
