Mo2C nanoparticles are embedded into graphite nanosheet (GNS) matrix via a simple carburization process. The structures of the as-prepared Mo2C/GNS hybrid are characterized by transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Raman, thermogravimetric analyses, and N-2 adsorption-desorption isotherm. Structural characterization results reveal strong coupling interaction of the Mo2C and carbon support. The resulting Mo2C/GNS is examined as electrocatalysts for hydrogen evolution reaction in neutral, acidic and alkaline solutions. Electrochemical results indicate that the Mo2C/GNS possesses outstanding activity as well as durability. At a current density of 10 mA cm(-2), overpotentials are determined to be 136, 82 and 73 mV in neutral, acidic and alkaline solutions, respectively. The superior performance of Mo2C/GNS is attributed to the strong coupling interaction of Mo2C and GNS support. (C) 2016 The Electrochemical Society. All rights reserved.
