Graphene- and Phosphorene-like Boron Layers with Contrasting Activities in Highly Active Mo2B4 for Hydrogen Evolution
Two different boron layers, flat (graphene-like) and puckered (phosphorene-like), found in
the crystal structure of Mo2B4 show drastically different activities for hydrogen evolution,
according to Gibbs free energy calculations of H-adsorption on Mo2B4. The graphene-like B
layer is highly active, whereas the phosphorene-like B layer performs very poorly for
hydrogen evolution. A new Sn-flux synthesis permits the rapid single-phase synthesis of
Mo2B4, and electrochemical analyses show that it is one of the best hydrogen evolution …
