Abstract Water‐splitting reactions such as the hydrogen evolution reaction (HER) and oxygen (OER) typically require expensive noble metal‐based electrocatalysts. This has motivated researchers to develop novel, cost‐effective electrocatalytic systems. In this study, a new multicomponent nanocomposite was assembled by combining functionalized multiwalled carbon nanotubes, Cu‐based metal–organic framework (MOF) (HKUST‐1 or HK), sulfidized NiMn‐layered double hydroxide (NiMn‐S). The resulting nanocomposite, abbreviated MW/HK/NiMn‐S, features unique architecture, high porosity, numerous electroactive Cu/Ni/Mn sites, fast charge transfer, excellent structural stability, conductivity. At current density of 10 mA cm −2 , dual‐function electrocatalyst shows remarkable performance, with ultralow overpotential values 163 mV 73 (HER), well low Tafel slopes (57 75 dec −1 respectively). Additionally, its turnover frequency (4.43 s for OER; 3.96 HER) are significantly superior those standard Pt/C IrO 2 synergistic effect nanocomposite's different components is responsible enhanced performance. A functional theory study revealed that multi‐interface heterostructure contribute increased electrical conductivity decreased energy barrier, in HER/OER activity. presents novel vision designing advanced electrocatalysts performance water splitting.

Fe-doped Ni (oxy)hydroxide shows intriguing activity toward oxygen evolution reaction (OER) in alkaline solution, yet it remains challenging to further boost its performance. In this work, a ferric/molybdate (Fe3+ /MoO42- ) co-doping strategy is reported promote the OER of oxyhydroxide. The reinforced Fe/Mo-doped oxyhydroxide catalyst supported by nickel foam (p-NiFeMo/NF) synthesized via unique plasma etching-electrochemical doping route, which precursor Ni(OH)2 nanosheets are first etched form defect-rich amorphous nanosheets, followed electrochemical cycling trigger simultaneously Fe3+ and phase transition. This p-NiFeMo/NF requires an overpotential only 274 mV reach 100 mA cm-2 media, exhibiting significantly enhanced compared NiFe layered double hydroxide (LDH) other analogs. Its does not fade even after 72 h uninterrupted operation. situ Raman analysis reveals that intercalation MoO42- able prevent over-oxidation NiOOH matrix from β γ phase, thus keeping at most active state.
