The mutual conversion of heat energy and surface energy during the adsorption and desorption of working fluids on the surface of nano-porous materials can improve the heat storage capacity for energy storage. In this paper, the energy storage properties of two industrial fluids, HFO-1336mzz(Z) and Hexamethyldisiloxane(MM),with MOF-200 nanoparticle, were investigated by means of molecular dynamics simulations and grand canonical Monte Carlo simulations. It shows that the adsorption capacity of HFO-1336mzz(Z) in MOF is higher than that of MM. Moreover, the increment ratio of thermal energy storage properties of HFO-1336mzz(Z)/MOF-200 mixture is better than that of MM/MOF-5 mixture.
