An adsorption heat pump has recently emerged as energy-efficient heating and cooling system. The amount of adsorbed working fluids is an important factor at low-grade temperatures to utilize waste heat and thermal energy storage. Metal-organic frameworks(MOFs) are regarded as promising adsorbents due to their large specific surface area, tunable pore size, and pore chemical properties. However, there have been few reports that investigated ammonia uptake performance with MOFs and their nanocomposite at high ammonia pressures in low working temperatures. Herein, we developed a hybrid nanocomposite with a MOF and reduced graphene oxide(rGO) composite through a one-pot hydrothermal reaction. Its ammonia adsorption capacity was evaluated under high ammonia pressures, which showed that the nanocomposite with 3.7% rGO could have higher ammonia adsorption capacity than pure MOF.
