开发稳定的氧还原电催化剂仍然是燃料电池和金属-空气电池商业化的关键挑战。最近在Joule，Lin和同事构建了中空多孔尖晶石AB 2 O 4微球（A = Zn，B = Mn/Co）作为有效和持久的氧还原电催化剂，并发现Co 3+自旋态的电子跃迁在提高催化性能中的重要性。
Developing robust oxygen reduction electrocatalysts is still a critical challenge for the commercialization of fuel cells and metal-air batteries. Recently inJoule, Lin and colleagues constructed hollow porous spinel AB2O4microspheres (A = Zn, B = Mn/Co) as efficient and durable oxygen reduction electrocatalysts and found the importance of the electronic transition of the spin state of Co3+in boosting the catalytic performance.
