Electrocatalytic Water Splitting: Cation‐Modulated HER and OER Activities of Hierarchical VOOH Hollow Architectures for High‐Efficiency and Stable Overall Water Splitting (Small 47/2019)

In article number 1904688, Jian Zhang, Xing'ao Li, and co-workers present atom-scale modulation of electronic regulation in nonprecious-based electrocatalysts VOOH-3Fe (3% Fe, mole ratio) exhibiting a low overpotential of 90, 195 and 300 mV at the current density of 10 mA cm−2 for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and overall water splitting in alkaline media, respectively.
