Atomically thin hexagonal boron nitride (BN) crystals as efficient co-catalysts can enhance both the activity and stability of electrochemical oxygen evolution reactions. However, their practical use has been limited by the existing assembly methods incompatible with complex three-dimensional electrocatalysts. In this work, we develop an electrophoretic deposition strategy to firmly attach liquid-exfoliated BN nanosheets onto nanostructured NiFe-layered double hydroxide (LDH) electrodes, achieving a current density of 1000 mA cm-2 at an overpotential of 318 mV and maintaining stability for over 240 h. This work provides a feasible approach for integrating BN nanosheets into electrocatalytic systems, extendable to other low-dimensional materials.
