New perspectives in hydrogen storage based on RCH2NH2/RCN couples

Abstract

A recent breakthrough in primary amine dehydrogenation by an oxidant-free process, and without any hydrogen acceptor, opens the possibility for RCH₂NH₂/RCN couples to be considered as potential hydrogen energy carriers. Both hydrogenation and dehydrogenation processes can be catalysed by ruthenium complexes under rather mild conditions. This emerging exciting approach could be the starting point for the development of valuable economical systems.
