Water Splitting: Synergism of Geometric Construction and Electronic Regulation: 3D Se‐(NiCo)S_x/(OH)_x Nanosheets for Highly Efficient Overall Water Splitting (Adv. Mater. 12/2018)

In article number 1705538, Jinlong Gong and co-workers from Tianjin University describe the construction of ultrathin defect-enriched three-dimensional Se-(NiCo)Sx/(OH)x nanosheets for overall water splitting through a facile Se-induced hydrothermal treatment. Through morphological optimization, defect engineering, and tailoring of the electronic structure, the nanosheets deliver a current density of 10 mA cm−2 for ≈66 h without obvious...
