Summary: The coordination chemistry of the Ru-N(O)-C moieties in carbon-supported Ru heterostructured electrocatalysts can be precisely modulated to achieve enhanced electrocatalytic performance in hydrogen evolution reaction. The optimal heterostructured electrocatalyst demonstrates the highest specific activity among reported Ru-based electrocatalysts, surpassing the state-of-the-art Pt/C catalyst in alkaline media. The atomic-level interface engineering of carbon-supported Ru-based heterostructures not only promotes H2O adsorption and dissociation, but also enhances the adsorption behavior of H on metallic Ru species, leading to accelerated hydrogen evolution kinetics in both alkaline and acidic media.

Summary: This study systematically investigates the role of transition metal-functionalized N-doped carbon nanosheets as multifunctional electrocatalyst supports for hydrogen evolution/oxidation reactions in alkaline media. The results show that all the M-N-C nanosheets, except Cu-N-C and Ag-N-C, can promote the alkaline HER/HOR electrocatalytic activity of Pt, with Mn playing a more significant role. The promotion effect of the M-N-C support is closely associated with the electronegativity of the metal dopants and the filling degree of their d-orbitals.
