【Abstract】 A self-supporting three-dimensional structure Ru/NiFe LDH/Ni Foam bifunctional catalyst was prepared by hydrothermal and one-step reduction methods. Because Ru/NiFe LDH/Ni foam has a three-dimensional structure, this array-type three-dimensional structure is conducive to gas desorption, and a large specific surface area provides more active sites. These characteristics are conducive to improving the catalytic performance of the catalyst. In 1 M KOH medium, the overpotential of the oxygen evolution reaction（OER） of the Ru/NiFe LDH/Ni foam catalyst is 228 mV at a current density of 10 mA·cm^-2, and the overpotential of the hydrogen evolution reaction（HER） is 66 mV at a current density of 10 mA·cm^-2. The catalyst has a potential of 1.70 V at a current density of 10 mA·cm^-2 in a two-electrode system for complete water splitting.更多还原
