cobalt-based electrocatalysts

The oxygen reduction reaction (ORR) is crucial in fuel cells and metal-air batteries. It proceeds via both four-electron and two-electron pathways, producing water and hydrogen peroxide, respectively. Precise control over ORR selectivity is key. Cobalt-based electrocatalysts have become a research hotspot due to their high activity, low cost, and ease of synthesis. High selectivity can … Read more
