The development of cost-effective, sustainable, and efficient catalysts for liquid organic hydrogen carrier systems is a significant goal. However, all the reported liquid organic hydrogen carrier systems relied on the use of precious metal catalysts. Herein, a liquid organic hydrogen carrier system based on non-noble metal catalysis was established. The Mn-catalyzed dehydrogenative coupling of methanol and N,N'-dimethylethylenediamine to form N,N'-(ethane-1,2-diyl)bis(N-methylformamide), and the reverse hydrogenation reaction constitute a hydrogen storage system with a theoretical hydrogen capacity of 5.3 wt%. A rechargeable hydrogen storage could be achieved by a subsequent hydrogenation of the resulting dehydrogenation mixture to regenerate the H2-rich compound. The maximum selectivity for the dehydrogenative amide formation was 97%.

基于锰催化的（脱）氢化作用，甲醇-二胺和二酰胺之间可逆的相互转化，用于储氢。

开发用于液态有机氢载体系统的具有成本效益，可持续和高效的催化剂是一个重要目标。然而，所有报道的液态有机氢载体系统都依赖于贵金属催化剂的使用。在此，建立了基于非贵金属催化的液态有机氢载体体系。Mn与N，N'-二甲基乙二胺的Mn催化脱氢反应形成N，N'-（乙烷-1,2-二基）双（N-甲基甲酰胺），逆加氢反应构成了一个氢存储系统理论氢容量为5.3重量％。通过随后对所得脱氢混合物进行氢化以再生富含H 2的化合物，可以实现可再充电的氢存储。脱氢酰胺形成的最大选择性为97％。
