| Abstract | The exploration of efficient and economical electrocatalysts towards the oxygen evolution reaction (OER) is highly imperative for the development of OER-associated sustainable energy technologies. Interface engineeringenabled electronic regulation represents a powerful leverage to improve the intrinsic activity of earth-abundant electrocatalysts. Herein, we report a scalable hydroxycarbonate-assisted pyrolysis strategy to immobilize Janusstructured fine Ni/Ni2P nanoparticles onto hierarchical N-doped carbon nanosheet-grafted nanofibers (denoted as Ni/Ni2P@N-CNIF hereafter) for high-efficiency electrocatalytic OER. The strong coupling of fine Ni/Ni2P hetem-nanoparticles with the superstructured carbon substrate renders Ni/Ni2P@N-CNIF with regulated electronic state, sufficient anchored active sites, shortened distance for mass transport and enhanced structural stability. Consequently, the optimized Ni/Ni2P@N-CNIF exhibits extraordinary electrocatalytic OER activity and durability in KOH medium. As a proof-of-concept demonstration, when pairing Ni/Ni2P@N-CNIF with commercial Pt/C catalyst for overall water splitting, the assembled two-electrode electrolyzer outperforms the stateof-the-art RuO2 parallel to Pt/C-equipped counterpart. The concept of interface engineering and carbon hybridization herein may provide new inspirations for the future design of affordable and efficient electrocatalysts for various sustainable energy conversions. |
