Immobilization of Ni₃Co Nanoparticles into N‐Doped Carbon Nanotube/Nanofiber Integrated Hierarchically Branched Architectures toward Efficient Overall Water Splitting

Exploring cost-effective and high-performance bifunctional electrocatalysts for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is of paramount importance for the advancement of H2 production technology, yet remains a huge challenge. Herein, a simple electrospinning-pyrolysis strategy is developed to directly immobilize uniform Ni3Co nanoparticles into a hierarchical branched architecture constructed by in situ formed...
