Atomic-level insight into super-efficient electrocatalytic oxygen evolution on iron and vanadium co-doped nickel (oxy)hydroxide.
Jian Jiang,Fanfei Sun,Si Zhou,Wei Hu,Hao Zhang,Jin-Chao Dong,Zheng Jiang,Jijun Zhao,Jian-Feng Li,Wensheng Yan,Mei Wang +10 more
TL;DR: Density functional theory calculations indicate that the vanadium site of the iron/vanadium co-doped nickel (oxy)hydroxide gives near-optimal binding energies of oxygen evolution reaction intermediates and has lower overpotential compared with nickel and iron sites.
