Ni-based layered double hydroxides (Ni-LDH) is regarded as one of the most promising electrocatalyst for hydrogen evolution reaction (HER). To further improve the HER performance of Ni-LDH, it is important to provide more active sites and decrease reaction energy. Herein, bimetal NiFe-LDH derived from NiFe-MIL was constructed by two-steps hydrothermal strategy. NiFe-LDH-0.3 displays the excellent HER activity, which achieves a low overpotential of 148 mV at 10 mA·cm-2. This work offers a novel strategy to design and develop highly efficient electrocatalyst via for HER activity and other energy conversion application.
