Abstract
Official abstract text for this publication.
The composite adsorbent for an adsorption chiller is a composite material formed from multi-walled carbon nanotubes incorporated into a metal organic framework, where the metal organic framework is MIL-101(Cr). The MIL-101 family of metal organic frameworks include terephthalate (benzene 1,4-dicarboxylate) linkers and M3O-carboxylate trimers (M=Cr or Fe) with octrahedrally coordinated metal ions binding terminal water molecules. MIL-101 frameworks having a crystal structure with very large pore sizes (29 and 34 Angstroms) and surface area, and are known to have a large water uptake. However, metal organic frameworks have low thermal conductivity due to the presence of organic matter, resulting in lower heat transfer rates and greater cycle time, and are not stable in aqueous media or disintegrate slowly upon recurrent hydrothermal cycling. Composite binding with multi-wall carbon nanotubes improves heat transfer characteristics and thermal stability.
