The development of platinum group metal‐free catalysts for the oxygen reduction reaction (ORR) is critical to advancing sustainable energy conversion technologies. Manganese (Mn)‐based catalysts, known for their reduced toxicity and promising durability, have traditionally exhibited lower ORR activi...
