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

ABSTRACT: 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 N-doped carbon-nanotube-grafted carbon nanofibers. The elaborate construction of such hybrid hierarchical architecture can effectively modulate the electronic structure of the active sites, enlarge the exposure of active sites, and facilitate the electron transfer and mass diffusion, favoring both the HER and OER. As a result, the optimized catalyst
