Hydrothermal temperature-driven evolution of morphology and electrocatalytic properties of hierarchical nanostructured CoFe-LDHs as highly efficient electrocatalysts for oxygen evolution reactions

, as well as an ultra-long durability (97 h) in 1 M KOH electrolyte. Therefore, the design of a unique hierarchical nanostructure by tuning the reaction conditions may open up a new avenue for high-performance OER electrocatalysts.
