A 3D-hierarchical flower like architecture of anion induced layered double hydroxides for competing anodic reactions

In this study, the partially sulfurized CoFeLDH was synthesized by using Na₂S as the sulfur source. The catalyst performed excellently for UOR & OER requiring a lower overpotential of 171 and 268 mV at the current density of 40 mA cm⁻², respectively, with the prolonged stability of more than 100 h.
