NiFe-based (oxy)hydroxides are the benchmark catalysts for oxygen evolution reaction (OER) in alkaline medium, however, it is still challenging to control their structures and compositions. Herein, molybdates (NiFe(MoO4 )x ) applied as unique precursors synthesize ultrafine Mo modified NiFeOx Hy (oxy)hydroxide nanosheet arrays. The electrochemical activation process enables molybdate ions (MoO42- gradually dissolve, at same time, hydroxide (OH- electrolyte diffuse into precursor react with Ni2+ Fe3+ confined space produce nanosheets (<10 nm), which densely arranged microporous arrays maintain rod-like morphology of precursor. Such dense rich edge planes on surface expose more active sites. More importantly, capillary phenomenon hydrophilic hydroxyl groups induce superhydrophilicity rough produces superaerophobic characteristic bubbles. With these advantages, optimized catalyst exhibits excellent performance OER, a small overpotential 182 mV 10 mA cm-2 long-term stability (200 h) 200 . Theoretical calculations show that modification enhances electron delocalization optimizes adsorption intermediates.

Abstract The design of catalysts with tunable active sites in heterogeneous interface structures is crucial for addressing challenges the water‐splitting process. Herein, a hollow spherical heterostructure FeCo‐P successfully prepared by hydrothermal and phosphorization methods. This structure, along between Co 2 P FeP, not only facilitates exposure more sites, but also increases contact area catalyst electrolyte, as well shortens distance mass/electron transfer. enhancement promotes electron transfer to facilitate water decomposition. exhibits excellent hydrogen evolution (HER) oxygen (OER) performance when reaching @ 10 mA cm −2 1 mol L −1 KOH, overpotentials 131/240 mV HER/OER. Furthermore, used both cathode anode overall splitting (OWS), it requires low voltages 1.49, 1.55, 1.57 V achieve CDs 10, 100, 300 , respectively. Density functional theory calculations indicate that constructing FeP good lattice matching can redistribution, thereby enhancing electrocatalytic OWS. work opens up new possibilities rational efficient electrolysis derived from MOFs.
