Abstract
Amorphous and multilevel two-dimensional Ni(OH)2·0.75H2O@Ni(OH)2/FeOOH heterojunction nanosheets with efficient OER catalytic activity (only 270 mV overpotential at 100 mA cm−2 and very low Tafel slope of 44 mV dec−1) and outstanding stability (more than 100 h at 100 mA cm−2) were synthesized, the electrocatalytic properties of which could be adjusted through regulating the Ni electronic structure by doping Fe element.
