AB - Electrocatalysis is at the heart of energy conversion in sustainable energy systems, during which the involved electrocatalysts usually undergo dynamic reconstruction. Such reconstruction normally leads to structure corrosion and collapse which lower the electrochemically active surface area, blocks the diaphragm and increases the internal resistance of the electrolyzer, collectively resulting in inferior energy conversion efficiency. Herein, we report an efficient polyaniline (PANi) confining strategy to address the above issues using Ni5P4 for the oxygen evolution reaction (OER) as an example. Experiments and DFT computations reveal that the elastic PANi can adaptively buffer the structure corrosion of Ni5P4 during oxidative reconstruction and positively charge the reconstruction‐formed nickel (oxy)(hydr)oxides for optimal binding of OER intermediates, jointly leading to significantly improved performance featuring a long‐term stability at 100 mA cm−2 with a low overpotential of only 280 mV. This facile strategy can be effectively extendable to other compound catalysts in electrocatalytic reactions.
