Abstract The layered double hydroxide (LDH) captivates the starlight of electrochemical water‐splitting applications due to its stacked layers and larger surface area. A novel approach is reported integrate CoFe‐LDH/NiAl‐LDH heterostructure through a single‐step in situ transmogrification, harnessing benefits LDH. Raman spectroscopy reveals that aluminum (Al) doping promotes formation high‐valent Co III/IV ‐O active species concentration LDH, whereas without Al dopants, catalyst predominantly exhibit Ni II/III underperform catalytic activity. projected density states very close Fermi level positions Al‐doped samples which significantly enhance electron transfer processes. Mott–Schottky studies confirm both Al40 CoFe30 Al60 CoFe20 catalysts are p‐type semiconductors, exhibiting distinct redox behaviors under applied bias. At positive bias, undergoes downward band bending (accumulation), align Fermi‐level near water oxidation potential, oxygen evolution reaction (OER). negative bias causes upward (deep depletion) CoFe30, shifts reduction hence facilitates hydrogen (HER). Overall, this study highlights importance manipulating alignment LDH strategic metal achieve targeted reactions.
