Abstract
Industrial hydrogen production via water electrolysis is critically limited by the oxygen evolution reaction (OER), especially at high current densities (>500 mA cm−2) where conventional NiFe electrocatalysts fail due to poor conductivity and mass transport. We overcome this barrier through a transformative nanoengineering strategy, namely, of boron-doped, mesoporous NiFe alloy nanosheets directly grown on carbon cloth (m-NiFe-CC). This approach uniquely leverages dimethylamine borane as a dual reducing agent/boron dopant and Brij 56 surfactant to create ordered 5–7 nm mesopores, enabling efficient mass/charge transport. The optimized m-NiFe-CC achieves record-low overpotentials of 225, 270, and 329 mV at 10, 100, and 500 mA cm−2 outperforming state-of-the-art NiFe catalysts, while exhibiting an 8-fold higher turnover frequency (0.7 s−1 at 300 mV) and exceptional 100-h stability at industrial-grade current density. In situ surface reconstruction forms conductive NiFeB cores and active NiFeOOH phases, driven by boron-mediated electronic modulation. This work establishes a scalable paradigm for nanoscale architectural control in high-current-density electrocatalysis, bridging fundamental innovation with industrial green hydrogen production.
