Although the development and application of a BNHx -waste recycling process is one of the major prerequisites for the use of ammonia borane as hydrogen source material, most research groups in the field have focused on AB hydrogen release and only few groups have worked on the development of energetically viable recycling schemes. In our work we target the development of a closed recycling process containing three desired steps: superacid break-up of the BNHx -waste, catalytic hydrodehalogenation of the generated boron halide, and base-exchange between Et3 NBH3 and ammonia. Catalytic hydrodehalogenation provides a convenient means to generate B-H bonds using molecular hydrogen, avoiding potentially energetically expensive reduction reagents.

用HBr / AlBr3和其他基于HX / AlX3的方案回收废氨硼烷。

尽管BNHx废物回收工艺的开发和应用是使用氨硼烷作为氢源材料的主要先决条件之一，但该领域中的大多数研究小组都专注于AB氢的释放，只有极少数小组致力于该过程的开发。可行的回收计划。在我们的工作中，我们的目标是开发包含三个所需步骤的密闭循环工艺：BNHx废物的超酸分解，生成的卤化硼的催化加氢脱卤作用以及Et3 NBH3与氨之间的碱交换。催化加氢脱卤为使用分子氢产生BH键提供了一种方便的方法，避免了可能在能源上昂贵的还原剂。
