Copper-Catalyzed Hydrogen Production through the Dehydrogenative Coupling of Methanol and Diamine.

A hydrogen storage system was developed via heterogeneous catalysis, employing the dehydrogenative coupling of methanol and N,N'-dimethylethylenediamine to efficiently produce high-purity H2. In this process, the Cu/ZnO/Al2O3 catalyst displayed superior activity in hydrogen production, with Cu+ identified as the major active site through comprehensive characterization.
