Synergistic effect of Co-Ni co-bridging with MoS₂ nanosheets for enhanced electrocatalytic hydrogen evolution reactions.

ABSTRACT: The depletion of fossil fuels and associated environmental problems have drawn our attention to renewable energy resources in order to meet the global energy demand. Electrocatalytic hydrogen evolution has been considered a potential energy solution due of its high energy density and environment friendly technology. Herein, we have successfully synthesized a noble-metal-free Co-Ni/MoS₂ nanocomposite for enhanced electrocatalytic hydrogen evolution. The nanocomposite has been well characterized using HRTEM, elemental mapping, XRD, and XPS analysis. The as-synthesized nanocomposite exhibits a much smaller onset potential and better current density than those of Co-MoS₂, Ni-MoS₂ and MoS₂, with a Tafel value of 49 mV dec^-1, which is compar
