Tóm tắt

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 synergistic electronic contact between the Ru and NiFe LDH led to the exceptional OER performance with the low overpotential of 196 mV at 10 mA cm
