Narrowing High‐Valent Ni Formation Potential and Widening Urea Oxidation Window by Ni 2 P/MoP Hybrid Catalyst

ABSTRACT Achieving selective and energy‐efficient urea oxidation is a key challenge in urea‐assisted water electrolysis due to sluggish activation of nickel sites and their limited active potential range. Here, we construct Ni 2 P/MoP embedded in conductive carbon nanofibers (Ni 2 P/MoP/CNFs) that couple precise interfacial charge redistribution with synergistic electronic modulation to accelerate high‐valent Ni 3+ sites formation (50 vs. 140 mV of Ni 2 P) and expand urea oxidation potential win
