Key Points

This research aims to develop sorbents that effectively capture CO₂ at low concentrations while ensuring efficient transport and compatibility with contactor structures.
Developed hierarchically structured MIL-100(Al) beads.
Assessed material properties for CO₂ capture efficiency.
Evaluated mass transport characteristics and structural compatibility with air capture systems.
Demonstrated high CO₂ affinity at ultradilute concentrations.
Achieved improved mass transport rates compared to traditional sorbents.
Showed structural compatibility with practical contactor designs.

Implication

Evaluates amine sorbents’ efficiency in capturing CO₂, suggesting better solutions for direct air capture.

Abstract

Direct air capture (DAC) demands sorbents that integrate high affinity for CO₂ at ultradilute concentrations with efficient mass transport and structural compatibility with practical contactors. However, most amine-functionalized metal-organic frameworks...
