An electrospinning strategy to fabricate an integrated electrode with multiple components for highly efficient electrocatalytic water splitting

Abstract

Herein, a novel multi-component electrocatalyst that integrates CuCo-MnO nanoparticles (NPs), carbon nanotubes and electrospun carbon nanofibers (CuCo-MnO@CNTs/CNFs) was prepared by combining electrospinning technology and an NH₃ assisted graphitization process. The self-supported CuCo-MnO@CNTs/CNFs achieves impressive catalytic activity with overpotentials of 33 and 184 mV at 10 mA cm⁻² for the HER, and 180 mV and 250 mV for the OER at 10 mA cm⁻² in both acidic and alkaline solutions, respectively.
