Inducing strain in the lattice effectively enhances intrinsic activity of electrocatalysts by shifting metal's d-band center and tuning binding energy reaction intermediates. NiFe-layered double hydroxides (NiFe LDHs) are promising for oxygen evolution (OER) due to their cost-effectiveness high catalytic activity. The distorted β-NiOOH phase produced Jahn-Teller effect under oxidation polarization is known exhibit superior activity, but it eventually transforms undistorted γ-NiOOH during OER process. Such a reversible distortion limits In this study, we propose facile boron tungstate (BWO) anion intercalation method induce irreversible NiFe LDHs, leading significantly enhanced Strong interactions with BWO anions significant stress on LDH's metal-hydroxide slab, an expansion metal-oxygen bonds subsequent distortion.
