MFM-300(Al/Fe/Cr/V) as high-performance water-adsorption sorbents for cooling and refrigeration
Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC12006999/
Open-access (PMC), JACS 2025, primary data.
Key findings
- COP 0.8 at ultralow driving/regeneration temperature 62-64 C (both AC and refrigeration modes), across four isostructural metal variants.
- Water uptake 0.31-0.34 g/g at 30 C, P/P0=0.3; heat of adsorption ~49 kJ/mol (easy regeneration).
- Working capacity DeltaW 0.31-0.35 mL/mL (AC), 0.27-0.31 mL/mL (refrigeration) at Tdes=64 C.
- Hydrothermal stability: full capacity after 1-month water soak, 5-day boiling water, 20 ad/desorption cycles.
- Compares favorably vs SAPO-34 (0.29 g/g) and MIL-160/CAU-10/MOF-303.
- Beats the EMM-8 benchmark (COP 0.85 @ 63 C) on driving temp while adding proven cycling stability.
