Tailoring nanostructured NiFe-LDH catalysts via ammonium fluoride-mediated hydrothermal synthesis: enhanced electrocatalytic performance in oxygen evolution reactions

Optimizing the NH 4 F content in NiFe-layered double hydroxides (LDHs) significantly enhances their OER performance by tuning the microstructure and electronic properties, with a higher proportion of high-valent cations improving catalytic efficiency.
