Hitherto, reducing the amount of Pt and improving the efficiency of hydrogen evolution reaction (HER) in alkaline media is still a key issue for industrial production of hydrogen. In this work, electrochemical deposition was employed to load trace amount of Pt species onto NiCo layered double hydroxides (NiCo-LDHs) prepared by hydrothermal reaction on a nickel foam substrate. NiCo-LDHs can promote the dissociation of water in alkaline media, and Pt sites are beneficial for the binding and desorption of H on the electrode surface. The combination of Pt and NiCo-LDHs effectively paves a new way to enhance the slow kinetics of hydrogen evolution reaction of Pt in an alkaline media. The hybrid catalyst Pt-NiCo-LDHs shows significantly improved HER performance, with an overpotential of 56 mV to drive a typical current density of 10 mA?cm-2 in alkaline media at an ultra-low Pt loading of 30.4 ug?cm-2. The mass activity of Pt-NiCo-LDHs is 5.6 times higher than commercial Pt/C catalyst at an overpotential of 100 mV. Moreover, the Pt-NiCo-LDHs exhibits outstanding stability after 100 h test.
