Owing to their high uptake capacity at low temperature and excellent reversibility kinetics, metal-organic frameworks have attracted considerable attention as potential solid-state hydrogen storage materials. In the last few years, researchers have also identified several strategies for increasing the affinity of these materials towards hydrogen, among which the binding of H(2) to unsaturated metal centers is one of the most promising. Herein, we review the synthetic approaches employed thus far for producing frameworks with exposed metal sites, and summarize the hydrogen uptake capacities and binding energies in these materials. In addition, results from experiments that were used to probe independently the metal-hydrogen interaction in selected materials will be discussed.
由于金属有机框架在低温下具有高吸附容量和出色的可逆动力学，它们作为潜在的固态储氢材料已引起了相当大的关注。在过去几年中，研究人员还确定了几种提高这些材料对氢的亲和力的策略，其中H₂与不饱和金属中心的结合是最有前景的策略之一。在此，我们综述了迄今为止用于制备具有暴露金属位点的框架的合成方法，并总结了这些材料中的氢吸附容量和结合能。此外，还将讨论用于独立探测选定材料中金属-氢相互作用的实验结果。
