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. Also, demonstrated remarkable stability over 50 h, utilizing chronoamperometry (CA) chronopotentiometry (CP). In addition, an integrated electrolyzer CFP-8/NF electrodes (polymeric binder-free electrodes) delivered cell voltage 1.65 V density 20 mA cm–2 accelerated kinetics stability, outperforming Pt/C (cathode)||RuO2 (anode) overall water splitting (OWSRs). coexistence Co, Fe, elements may accelerate electron mass movement, improving electrocatalytic performance. paves way further research into low-cost transition metal-based phosphides applications.
