The development of low-cost, long-lasting, and high-performance bifunctional electrocatalysts is needed for effective electrochemical water splitting. Herein, an interface-boration engineering strategy was used to synthesize heterostructured nickel borate–nickel oxide (Ni3(BO3)2–NiO) by using the electrospinning-incineration process, which exhibited unprecedentedly high electrocatalytic activity in alkaline media. Ni3(BO3)2–NiO electrode showed ultralow oxygen evolution reaction hydrogen overpotentials 261 150 mV, respectively, achieve 10 mA cm–2. For Ni3(BO3)2–NiO/NF-assisted as well solar-driven electrolyzers, a low cell voltage 1.60 V drive cm–2 their catalytic maintained 40 h, indicating significant potential use water-splitting. employed generate H2 effectively consuming power 732.33 LH2 kW h–1 lower than that cNiO (835 h–1). enhanced adsorption oxygen-containing Lewis base intermediates on acid–base interactions boosted performance. This work provides newer direction toward rational metal borate–metal heterostructure with excellent intrinsic characteristics energy applications, upscaled industrial-scale production due simplicity.
