Abstract

Herein, we report a low-cost ordered phase-transformation strategy to construct porous self-supported Ni/BaCO₃ electrodes with nanorod heterostructures. The optimized electrode achieves 36 mV at 10 mA cm⁻², approaching commercial Pt/C tested under identical conditions (20 mV), and maintains durability for over 500 h in 1 M KOH.
