Summary
A new solvent-free "explosive" synthesis method rapidly creates high-quality metal-formate frameworks. The nickel-formate framework shows excellent methane/nitrogen selectivity and capacity, outperforming other porous materials.
Area of Science:
- Materials Science
- Chemical Engineering
- Nanotechnology
Background:
- Metal-formate frameworks (MFFs) are advanced porous materials with diverse applications.
- Traditional synthesis methods can be time-consuming, costly, and environmentally impactful.
- Developing efficient and sustainable synthesis routes for MFFs is crucial.
Purpose of the Study:
- To introduce a novel solvent-free
- explosive
- synthesis (SFES) method for ultrafast and low-cost MFF production.
- To evaluate the adsorption performance of a synthesized nickel-formate framework (Ni-FA).
- To compare the performance of Ni-FA with existing state-of-the-art porous materials.
Main Methods:
- Solvent-free
- explosive
- synthesis (SFES) for rapid MFF generation.
- Experimental characterization of the synthesized nickel-formate framework (Ni-FA).
- Grand canonical Monte Carlo (GCMC) simulations for molecular modelling of adsorption performance.
Main Results:
- The SFES method successfully produced high-quality MFFs with permanent porosity.
- Ni-FA exhibited prominent methane/nitrogen selectivity (ca. 6.0).
- Ni-FA demonstrated a good methane adsorption capacity (ca. 0.80 mmol g-1) at 1 bar and 298 K.
Conclusions:
- The SFES method offers an ultrafast and cost-effective route to MFFs.
- Synthesized Ni-FA shows superior adsorption performance compared to many advanced porous materials.
- This work paves the way for scalable and sustainable production of high-performance MFFs.
