吸附辅助能量转换技术作为满足全球能源需求的可持续技术最近受到广泛关注。该技术的进步依赖于吸附材料的传质和传热性能的发展。MOF-801 是一种锆基微孔金属有机骨架（MOF），被认为是一种用于吸附辅助能量转换技术的有前途的吸附剂。本研究的重点是通过在框架中引入不同的过渡金属、镍和钴来增强 MOF-801 的吸水性能。在此，采用一锅溶剂热合成方法，通过用镍和钴部分取代 MOF-801 中的金属锆，合成了两种新型双金属 MOF。双金属 MOF，Ni-MOF-801 和 Co-MOF-801，发现与原始 MOF-801 同构。通过实验测量多孔特性，并观察到两种样品的总表面积和微孔表面积的增加。测量了样品的水吸附等温线，由于框架中两种金属的协同作用，与原始 MOF 相比，在低压区域观察到更大的亲和力。这种对水蒸气的更大亲和力导致有效净吸收和特定冷却效果的增加。在很宽的温度范围内通过实验测量了热物理性质，并在掺杂的 MOF-801 样品中发现了改进。Co-MOF-801 的性能优于原始 MOF-801，其特定冷却效果提高了 43%，可在相同工作条件下在 10°C 下提供高级冷却。

Adsorption-assisted energy conversion technologies are receiving extensive attention recently as a sustainable technology for meeting the worldwide energy demand. The advancement of this technology relies on the development of the mass and heat transfer properties of the adsorbent materials. MOF-801, a zirconium-based microporous metal organic framework (MOF), is regarded as a promising adsorbent for adsorption-assisted energy conversion technologies. This study focuses on enhancing the water sorption properties of MOF-801 by introducing different transitional metals, nickel, and cobalt, into the framework. Herein, two novel bimetallic MOFs were synthesized by partial substitution of the metal zirconium in MOF-801 with nickel and cobalt, employing a one-pot solvothermal synthesis method. The bimetallic MOFs, Ni-MOF-801, and Co-MOF-801, were found isostructural with the pristine MOF-801. Porous properties were measured experimentally, and an increment in total surface area and microporous surface area was observed for both samples. The water adsorption isotherm of the samples was measured, and a greater affinity at the lower pressure region was observed compared to the pristine MOF due to the synergistic effects of two metals in the frameworks. This greater affinity towards water vapor resulted in an increase in effective net uptake and specific cooling effect. The thermophysical properties were measured experimentally over a wide range of temperatures, and an improvement was found in the doped MOF-801 samples. Co-MOF-801 outperformed the pristine MOF-801 with a 43% improvement in specific cooling effect for delivering high-grade cooling at 10 °C with the same working conditions. The results will significantly contribute towards the development of high-performance next generation adsorption-based energy conversion systems.
