Method of storing hydrogen by forming a first ionic liquid by inducing a borohydride in a second ionic liquid comprising a cation and an anion comprising borate, and forming the second ionic liquid by releasing the hydrogen out of the first ionic liquid by using water and/or a catalyst, which method is characterized in that the first and the second ionic liquid are both water miscible and the second ionic liquid is separated, particularly is salted out, from solution in water by adding a separation inducer; certain ionic liquids for storing and releasing hydrogen comprising a borohydride or for preparing a ionic liquid for storing and releasing hydrogen comprising a borate; and a process for preparing ionic liquids for storing and releasing hydrogen comprising a borohydride.
通过在包含阳离子和包含硼酸盐的阴离子的第二离子液体中引入硼氢化物形成第一离子液体的方法来存储氢气,并通过使用水和/或催化剂从第一离子液体释放氢气形成第二离子液体,该方法的特征在于第一和第二离子液体均与水相溶,并且通过添加分离诱导剂从水溶液中分离第二离子液体,特别是通过盐析;某些用于存储和释放氢气的离子液体,包括硼氢化物,或用于制备含硼酸盐的存储和释放氢气的离子液体;以及用于制备含硼氢化物的存储和释放氢气的离子液体的过程。
