Amorphous and multilevel two-dimensional Ni(OH)·0.75HO@Ni(OH)/FeOOH heterojunction nanosheets with efficient OER catalytic activity (only 270 mV overpotential at 100 mA cm and very low Tafel slope of 44 mV dec) and outstanding stability (more than 100 h at 100 mA cm) were synthesized, the electrocatalytic properties of which could be adjusted through regulating the Ni electronic structure by doping Fe element.
合成了具有高效析氧反应(OER)催化活性(在100 mA cm⁻²时过电位仅为270 mV,塔菲尔斜率低至44 mV dec⁻¹)和出色稳定性(在100 mA cm⁻²下超过100小时)的非晶态和多级二维Ni(OH)₂·0.75H₂O@Ni(OH)₂/FeOOH异质结纳米片,其电催化性能可通过掺杂铁元素调节镍的电子结构来调控。
