摘要
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-2. Moreover, it features a modest Tafel slope of 24.9 mV dec-1. Importantly, this electrocatalyst sustains its robust stability during continuous electrolysis for 300 h at 500 mA cm-2. 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.
