Coating Thickness Effect on the Cyclic Performance of Aluminum and Zirconium Metal-Organic Frameworks for Heat Pump Application Ibrahim Albaik, Kamal Diab, Raya Al-Dadah, Saad Mahmoud, Mohamed A Ismail

Abstract

Metal-organic framework (MOF) is a promising adsorbent material to replace the conventional ones for many applications such as cooling and desalination. In this study, we report the effect of coating thicknesses using binder-agent aqueous solution-based synthesis strategy on the cyclic performance of aluminum and zirconium MOFs. The results showed that the coated MOFs enhances the cyclic performance over the neat granular and powdered forms. Moreover, the maximum effective coating thickness that provides faster cycle time compared to the neat adsorbent material is 0.85mm in aluminum MOF (aluminum fumarate), while it is 1.1mm in zirconium MOF (MOF-801). The enhancement of the coating thickness on the heat pump application is also studied.

Keywords Metal organic framework, aluminum fumarate, MOF-801 and water uptake.
