Ternary NiFeMn layered double hydroxides as highly-efficient oxygen evolution catalysts

Layered double hydroxides (LDHs) are a family of layer materials that receive heightened attention. Herein a ternary NiFeMn-LDH is investigated with superior oxygen evolution activity, which is attributed to the Mn4+ doping in the intralayer, which modifies the electronic structure and improves the conductivity of the electrocatalyst.
