NiFe LDH Hollow Nanocages Confined Ru Single Atoms for Remarkable Oxygen Evolution Reaction

Abstract Electrocatalysts with a hollow nanocage structure and single atoms (SAs) incorporated into layered double hydroxide (LDH) are highly significant for enhancing the efficiency of electrochemical water splitting. In this study, a highly efficient and robust electrocatalyst for the oxygen evolution reaction (OER) is successfully fabricated by confining Ru SAs within a hollow nanocage made of NiFe LDH. An etching and co‐precipitation method is used for making the NiFe LDH hollow nanocages and integrating the Ru atoms to produce Ru‐SAC/NiFe LDH. The nanocage architecture increases the surface area available for interaction and enhances the interface between the catalyst and electrolyte. The robust…
