Abstract
  • The metal-organic–framework MOF-5 is used as an adsorbent in advanced systems for vehicular hydrogen storage that are currently under development. Presently, these systems are limited by poor thermal conductivity of the adsorption bed, and thus our research addresses how the interfaces between grains of MOF-5 can be engineered to improve heat conduction. In this work we show that by understanding the dominant modes responsible for transmitting heat across the interface we design 3 different types of interface for MOF-5 model (by changing the surface termination), exposed node interface, linker-end interface and hydroxyl-end interface, as the possible results of synthesis and simulate the interfacial heat transport. We compare the simulation models in surface energy and structural stability to improve thermal conductivity by designing the interface.
