Defect-rich Cu nanowire-based/bimetallic oxide core-shell structure with low overpotential via oxygen evolution reaction

摘要

The materials with rich defects close to the Fermi level could regulate the electronic structure and improve the electrical conductivity,and subsequently enhance the catalytic activity and stability.In this study,Cu nanowire on Cu foam substrate supported bimetallic NiMn oxide nanosheets(NiMnOx NSs)were synthesized by a unipolar pulse electro-deposition(UPED)method to fabricate 3D hierarchical core-shell structure electrocatalysts and applied for OER in the water electrolysis.
