Electrochemically Activated Tetra-Metallic Phosphate (Mn–Fe–Co–Ni) Electrocatalyst for the Oxygen Evolution Reaction (OER) in Alkaline Media
The development of highly active and stable oxygen evolution reaction (OER) catalysts based on earth-abundant and low-cost metals remains a major challenge in the field of electrochemical water splitting. Previous studies have shown that metallic and bimetallic phosphates exhibit promising catalytic activity but often...
