Hybrids of Mn3O4 nanoparticles and hollow carbon spheres prepared from templated pyrolysis of polydopamine were assembled via a straightforward sonication procedure. The resulting hybrids exhibit excellent catalytic activity toward the oxygen reduction reaction (ORR) in prototype Zn–air batteries. Impressively, these catalysts exhibit higher discharge potential and exceptional stability when compared to commercial Pt–Ru catalysts while simultaneously showing comparable onset potential and maximum current density.

Mn3O4 纳米颗粒装饰的中空介孔碳球作为锌空气电池氧还原反应的有效催化剂
Mn 3 O 4纳米颗粒和由聚多巴胺模板化热解制备的中空碳球的混合物通过简单的超声程序组装。所得混合物对原型锌空气电池中的氧还原反应（ORR）表现出优异的催化活性。令人印象深刻的是，与商业 Pt-Ru 催化剂相比，这些催化剂表现出更高的放电电位和出色的稳定性，同时显示出相当的起始电位和最大电流密度。
