Abstract
- The quest for electrocatalysts that are both stable and efficient for seawater oxidation is intriguing yet presents significant challenges. Herein, we present a hierarchical NiFe-LDH@CoP core–shell array on carbon cloth (NiFe-LDH@CoP/CC) for efficient oxygen evolution reaction (OER) in an alkaline seawater electrolyte. The NiFe-LDH@CoP/CC array exhibits remarkably low overpotential of 251 mV to achieve current density of 500 mA cm<superscript>−2</superscript>. Moreover, it features a modest Tafel slope of 24.9 mV dec<superscript>−1</superscript>. Importantly, this electrocatalyst sustains its robust stability during continuous electrolysis for 300 h at 500 mA cm<superscript>−2</superscript>. The outstanding performance and unique hierarchical structure of the NiFe-LDH@CoP/CC array provides innovative insights for the development of efficient electrocatalysts tailored for seawater oxidation applications.
