HYDROGEN STORAGE

An amino acid is essential

Formic acid is a promising hydrogen carrier, but more effective and economical catalysis of both its synthesis from H2 and CO2 and its dehydrogenation is needed. To this end, a Mn-based complex, in the presence of an α-amino acid, is now shown to promote efficient catalysis of both reactions and enable retention and reuse of CO2.
