Abstract
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.
