Summary
Three new metal-organic frameworks (MOFs) with nia topology were synthesized for CO2 capture. JLU-MOF110(FeNi) showed the highest CO2 uptake and selectivity, making it promising for carbon capture applications.
Area of Science:
- Materials Science
- Chemistry
- Environmental Science
Background:
- Metal-organic frameworks (MOFs) are porous materials with tunable properties.
- Developing stable and selective MOFs for carbon capture is crucial for environmental remediation.
Purpose of the Study:
- To synthesize and characterize three novel isoreticular MOFs with nia topology.
- To evaluate their potential for CO2 capture and separation based on the hard-soft acid base (HSAB) theory.
Main Methods:
- Solvothermal synthesis of three MOFs: JLU-MOF110(In), JLU-MOF110(Fe), and JLU-MOF110(FeNi).
- Characterization of their structures, surface areas (BET), chemical stability (pH), and thermal stability.
- Evaluation of CO2 capture capacity and selectivity using gas adsorption isotherms and ideal adsorption solution theory (IAST).
Main Results:
- Three robust MOFs with nia topology were successfully synthesized.
- JLU-MOF110(FeNi) exhibited a neutral framework with a high BET surface area (808 m²/g) and superior CO2 capture capacity (99.6 cm³/g) and selectivity.
- All MOFs demonstrated high chemical and thermal stability across a wide range of pH and temperatures.
Conclusions:
- The synthesized MOFs are promising candidates for CO2 capture and separation.
- JLU-MOF110(FeNi) shows the best performance, particularly in dynamic column breakthrough experiments, highlighting its potential for industrial applications.
