| 英文摘要 | LiNi1-xFexO2 (0 <= x <= 0.3) and LiyNi0.8Fe0.2O2 (0.8 <= y <= 1.2) catalysts for the oxygen evolution reaction (OER) were systematically investigated to discover the influence of the composition and layered structure on electrochemical activity. LiNi0.8Fe0.2O2 exhibits OER activity that is better than that of LiNiO2 and other Fe substituted LiNiO2 catalysts, while Li1.2Ni0.8Fe0.2O2 shows OER activity that is much higher than that of LiNi0.8Fe0.2O2 and Li0.8Ni0.8Fe0.2O2 . The best OER activity is achieved on Li1.2Ni0.8Fe0.2O2 with a Tafel slope of 59 mV dec(-1) and a current density of 10 mA cm(-2) at an overpotential of 302 mV, better than that for the benchmark IrO2 catalyst. Combined with the density functional theory calculations, the enhanced OER activity is mainly attributed to the unique electronic structure derived from the interaction of Li, Ni, and Fe in the materials and the layered structure which plays an important role in stabilizing the high valence states of Ni and Fe during the OER. |
