The dependence of cathodic hydrogen evolution reaction (HER) on noble metal catalysts is a critical challenge to realizing the industrial-scale application of hydrogen production from electrochemical water splitting. Due to the excellent water dissociation catalytic ability of Mo2C and the high HER catalytic activity of MoOx, Mo2C/MoOxheterointerfaces are controllably constructed via hydrogen peroxide oxidation of Mo2C to achieve improved HER catalytic performance. On the Mo2C/MoOxheterointerface, protons generated by the Mo2C sites via water dissociation can be immediately reduced by adjacent MoOxsites via the Volmer step to promote the overall HER kinetics. As a result, the rationally designed heterointerface-rich Mo2C-O catalyst exhibits great HER activity with a low overpotential of 115 mV to deliver 10 mA/cm2current density. Along with great activity, the Mo2C-O catalyst also exhibits satisfying stability, confirming the promising application potential of the catalyst in industrial electrolysis systems.
