Outstanding efficiency and affordable electrocatalyst toward water splitting is of great essential to the development of hydrogen economy. However, the current water splitting device is seriously limited due to low and sluggish of its two half-reactions: Hydrogen evolution reaction (HER) and Oxygen evolution reaction (OER). Herein, an optimal design of Copper Molybdenum (CuMo2)/Graphene(GH) perform good bifunctional electrocatalytic activities toward HER and OER. The synthesis of was prepared by employing one-step hydrothermal method. N-CuMo2 nanoparticles are formed, and effectively decorated on graphene. The CuMo2/GH nanohybrid material was analyzed by using Scanning electron microscopy (SEM), nsmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy to confirm the formation of CuMo2/graphene, morphology, and chemical surface properties. In 1.0 M KOH, the catalyst exhibits low overpotential to reach high current density of 500 mA/cm2 for both HER and OER. This demonstrates the potential application of CuMo2/GH for practical water electrocatalysis. |
