Abstract

Exploring the role of surface hydrophilicity of non-precious metal N-doped carbon electrocatalysts in electrocatalysis is challenging. Herein we discover an ultra-hydrophilic non-precious carbon electrocatalyst, showing enhanced catalysis efficiency on both gravimetric and areal basis for oxygen reduction reaction due to a high dispersion of active centres.

摘要

探索非贵金属氮掺杂碳电催化剂的表面亲水性在电催化中的作用具有挑战性。在此，我们发现了一种超亲水的非贵金属碳电催化剂，由于活性中心的高度分散，在氧还原反应的重量和面积基础上均表现出增强的催化效率。
