abstract |
Adsorption heat pumps can be used for generating heating, cooling, seasonal energy
storage and water desalination applications. Metal-organic frameworks (MOFs) are hybrid
porous materials with high surface area and superior adsorption characteristics compared
to conventional adsorbents. MIL-101(Cr) has a large pore size with water vapour adsorption
capacity up to 1.5 g<sub>H2O</sub> g<sub>ads–1</sub> and high cyclic stability thus
has the potential to be used in adsorption heat pumps. This work investigates the
enhancement of the thermal conductivity and water adsorption characteristics of MIL-101(Cr)
using hydrophilic graphene oxide. Two methods have been used to develop MIL-101(Cr)/GrO
composites. The first method was through physical mixing between MIL-101(Cr) and GrO
while the other was through incorporating the GrO during the synthesis process of
MIL-101(Cr). The composites and MIL-101(Cr) were characterized in terms of their structure,
water adsorption uptake, BET surface area, particle size, thermal gravimetric analysis,
SEM images and thermal conductivity measurements. Results showed that introducing
low amounts of GrO (<2%) to the neat MIL-101(Cr) enhanced the water adsorption characteristics
at high relative pressure but enhanced the heat transfer properties by 20-30% while
using more than 2% of GrO reduced the water adsorption uptake but significantly enhanced
the thermal conductivity by more than 2.5 times. |
