▎ 摘　　要

NOVELTY - Synthesis of nickel-based layered structure electrocatalyst based on Mxene/graphene hydrogel electro-deposition comprises using MXene/RGO layered material and three-dimensional layered nickel-type LDH nano-sheet array grown on MXene /RGO substrate, where the nickel base LDH is a binary NiX-LDH or a ternary nickel-xyldh (X = cobalt, iron, aluminum, manganese, titanium) or a tetragonal nickel-XYLDH (Co, Fe, Al and/or Mn). USE - Synthesis method for preparing nickel-based layered structure electro-catalyst based on mxene/graphene hydrogel electro-deposition. ADVANTAGE - The unique three-dimensional layered structure is good for exposing more active sites, easy adsorption and desorption of hydrogen, improves the hydrogen production efficiency of the electrolytic water. The catalyst can realize efficient hydrogen evolution in alkaline electrolyte, with good chemical stability.
