The development of bifunctional electrocatalysts using renewable electricity for sustainable green energy industrial production is a potential method. As result, numerous standard methodologies investigate developing that naturally alter the electronic structure and minimize kinetic barriers. This study developed promising method engineering interfacial heterostructure nanoframes (Co2P/FeP-FeP4, hereafter denoted as CFP-8) deposited on nickel foam hydrothermal low-temperature phosphorization techniques. However, improved CFP-8 electrocatalyst was exposed to abundant active sites nanocrystals remained intact. Importantly, P incorporation plays crucial role in creating vacancy defect, which contributes thermodynamic favoring electrocatalysis oxygen evolution reaction (OER) intrinsically enhances hydrogen adsorption-free reactions (HERs), due interconnected arrangement via synergistic strain-induced effect. Therefore, enclosed demonstrate good performance display low overpotential with high current densities (HER, η10 = 97 mV, η20 131 η50 186 mV; OER, 230 247 280 mV) minimal Tafel value 111 mV/dec 74 HER OER under alkaline medium, superior benchmark electrocatalysts.

Abstract Electrochemical water splitting is a promising approach for sustainable hydrogen production, but the oxygen evolution reaction (OER) remains bottleneck due to sluggish kinetics, poor activity, and limited stability scalability. Here, Mo 2 N‐functionalized nickel designed foam (NF@Mo N) subsequently transform into N/NiSe/Ni P multi‐phase heterostructure through selenization phosphorization, address these challenges. The optimized NF@Mo catalyst integrates three key strategies: (I) functionalizing NF with N enhance conductivity charge transfer, (II) engineering collaborative multi‐interface optimize active sites (III) precisely controlling phase formation phosphorization mitigate surface reconstruction ensure long‐term stability. not only achieves an overpotential of 242 mV@10 mA cm −2 remarkable over 350 h, also low 395 mV at high current density 800 , outperforming pristine other control samples. Theoretical analysis reveals that N‐stabilized NiSe/Ni on enhances optimizes adsorption energies OER intermediates, leading improved catalytic performance This work provides new strategy designing high‐performance, non‐precious metal catalysts industrial applications advancing production.
