Anion‐Modulated HER and OER Activities of 3D Ni–V‐Based Interstitial Compound Heterojunctions for High‐Efficiency and Stable Overall Water Splitting

Overall water splitting driven by a low voltage is crucial for practical H 2 evolution, but it is challenging. Herein, anion-modulation of 3D Ni-V-based transition metal interstitial compound (TMIC) heterojunctions supported on nickel foam (Ni 3 N-VN/NF and Ni 2 P-VP 2 /NF) as coupled hydrogen ev…
