Abstract: A facile wet-chemical method for synthesizing two-dimensional Ru multilayered nanosheets with a superlattice is reported and the significance of the superlattice on electrocatalysis is demonstrated. Theoretical calculations reveal that the superlattice between the adjacent Ru layers can induce the strain effect, which leads to the lattice contraction and the weakening of the *H adsorption ability, as a result of improved HER performance.
