A novel and simple hydrogen storage system was developed, based on the dehydrogenative coupling of inexpensive ethylenediamine with ethanol to form diacetylethylenediamine. The system is rechargeable and utilizes the same ruthenium pincer catalyst for both hydrogen loading and unloading procedures. It is efficient and uses a low catalyst loading. Repetitive reversal reactions without addition of new catalyst result in excellent conversions in both the dehydrogenation and hydrogenation procedures in three cycles.
开发了一种新颖而简单的储氢系统，该系统基于廉价乙二胺与乙醇的脱氢偶联反应，生成二乙酰乙二胺。该系统可再充电，并且在加载和卸载氢气的过程中使用相同的钌钳形催化剂。它效率高，催化剂用量低。在不添加新催化剂的情况下，重复进行反转反应，导致在三个循环中脱氢和加氢过程都具有极好的转化率。
