Climate change is causing a rise in the need to transition from fossil fuels to renewable and clean energy such as hydrogen as a sustainable energy source. The issue with hydrogen's practical storage, however, prevents it from being widely used as an energy source. Current solutions, such as liquefied and compressed hydrogen storage, are insufficient to meet the U.S. Department of Energy's (US DOE) extensive on-board application requirements. Thus, a backup strategy involving material-based storage is required. Metal organic frameworks (MOFs) belong to the category of crystalline porous materials that have seen rapid interest in the field of energy storage due to their large surface area, high pore volume, and modifiable structure. Therefore, advanced technologies employed in the construction of MOFs, such as solvothermal, mechanochemical, microwave assisted, and sonochemical methods are reviewed. Finally, this review discussed the selected factors and structural characteristics of MOFs, which affect the hydrogen capacity.
气候变化导致从化石燃料向可再生清洁能源（如氢气作为可持续能源）转型的需求不断增加。然而，氢气实际储存方面的问题阻碍了它被广泛用作能源。目前的解决方案，如液化和压缩氢气储存，不足以满足美国能源部（US DOE）广泛的车载应用要求。因此，需要一种基于材料储存的备用策略。金属有机框架（MOF）属于晶体多孔材料类别，由于其大表面积、高孔隙率和可修饰的结构，在储能领域引起了迅速关注。因此，本文综述了用于构建MOF的先进技术，如溶剂热法、机械化学法、微波辅助法和声化学法。最后，本综述讨论了影响氢气储存容量的MOF选定因素和结构特征。
