Background:
- Carbon dioxide (CO2) emissions drive global warming, necessitating effective carbon capture and sequestration (CCS).
- Conventional CCS methods are energy-intensive and costly.
- Polymeric membranes show potential for CCS but suffer from permeability-selectivity trade-offs.
Purpose of the Study:
- To review various carbon capture and sequestration (CCS) methodologies.
- To elaborate on mixed matrix membranes (MMMs) as an efficient CCS technique.
- To discuss factors influencing MMM performance for gas separation.
Main Methods:
- Review of existing literature on CCS techniques.
- Analysis of mixed matrix membrane (MMM) composition and structure.
- Evaluation of MMM performance metrics, including permeability and selectivity.
Main Results:
- Mixed matrix membranes (MMMs) demonstrate superior gas separation performance compared to traditional polymeric membranes.
- Incorporating inorganic fillers like graphene oxide, zeolites, and metal-organic frameworks enhances MMM efficiency.
- Challenges remain, including interfacial defects and filler agglomeration, impacting selectivity.
Conclusions:
- MMMs present a cost-effective and energy-efficient alternative for CCS.
- Further research is needed to overcome fabrication and reproducibility challenges for industrial-scale MMM production.
