Nanosurface-induced construction of NiCoP–CoP heterostructure nanobristle electrodes for highly efficient alkaline hydrogen evolution reaction

J. Mater. Chem. A, 2023, Advance Article
DOI: 10.1039/D3TA04920E, Paper

NiCoP-CoP@NNA is a hierarchical heterostructured HER catalyst prepared by Ni solid-state diffusion from Ni nanowire substrate. DFT shows that Ni atoms diffuse from nano-sized substrate easily, and the heterostructure has a low water dissociation energy barrier, leading to better HER activity.
