摘要：
Adding porous nanoparticles into fluid can modify the energy storage properties of working fluid in the thermodynamic cycles. The adsorption capacity and thermal energy storage of CO2 in MOF-74 and UIO-66 at different temperatures and pressures are investigated in this paper via molecular simulations. The results denote that the adsorption of CO2 in the two studied metal organic frameworks (MOFs) differ from each other due to the different structures. The adsorption capacity of CO2 in MOF-74 is larger than that in UIO-66. However, the desorption heat of CO2 in MOF-74 is lower than that in UIO-66. Also, UIO-66 impacts more than MOF-74 on the thermal energy storage property of CO2.
