Pa级高真空环境仍面临挑战,其中氢气残余是导致真空失效的主要因素,亟需开发高性能低成本的氢吸附材料。本研究基于金属有机框架材料(MOFs)的多孔特性,采用HKUST-1作为新型氢吸附剂,系统研究其吸附特性及其在液氢罐箱(长12 192 mm、宽2 438 mm、高2 591 mm,40英尺)中的应用机制。结果表明:通过自主合成获得的具有1 426 m

Liquid-hydrogen tank containers have received increasing attention for hydrogen storage and transportation applications owing to their high hydrogen storage density and relatively low system cost. However, maintaining a high vacuum environment of 10

Pa in the interlayer of liquid-hydrogen containers remains challenging, with residual hydrogen contributing significantly to vacuum failure. Thus, high-performance, low-cost hydrogen adsorption materials and their corresponding vacuum maintenance mechanisms must be developed urgently. In this study, the adsorption characteristics of HKUST-1—a metal-organic framework—and its application mechanism in 40-foot (length: 12 192 mm, width: 2 438 mm, height: 2 591 mm)liquid hydrogen tank containers were investigated. The results show that the self-synthesized HKUST-1, with a specific surface area of 1 426 m

/g and a bimodal pore structure, exhibited excellent physical adsorption potential. The material demonstrated reversible hydrogen adsorption in the liquid-hydrogen temperature range and maintained effective adsorption at extremely low pressures, thus serving dual functions for both cryogenic and ambient-temperature adsorption. Dynamic vacuum model results reveal that using a small amount of HKUST-1 at the cold end of the interlayer reduce
d the required amounts of both cryogenic and ambient-temperature adsorbents, thereby effectively enhancing the physical adsorption of residual hydrogen and retarding the increase of H₂ partial pressure under extreme vacuum conditions. This study provides a new material solution for vacuum maintenance in liquid-hydrogen storage and transportation equipment, as well as offers valuable insights into the safety design and operation of liquid-hydrogen tank containers.
