Combined Exsolution and Electrodeposition Strategy for Enhancing Electrocatalytic Activity of Ti‐Based Perovskite Oxides in Oxygen and Hydrogen Evolution Reactions

The significant interest in perovskite oxides stems from their compositional and structural flexibility, particularly in the field of electrochemistry. In this study, the double E strategy (exsolution and electrodeposition strategies) is successfully devised for synthesizing perovskite-based bifunctional electrocatalysts, enabling simultaneous OER and HER applications with exceptional catalytic performance. The synthesized R-LCTFe/Ni catalyst exhibits outstanding electrocatalytic activity, delivering low overpotentials of 349 and 309 mV at 10 mA cm
