One-pot synthesis of iron–nickel–selenide nanorods for efficient and durable electrochemical oxygen evolution†
Abstract
Iron–nickel–selenide (Fe–Ni–Se) nanorods have been fabricated by a one-pot solvothermal selenization process. The Fe–Ni–Se nanorods grown on nickel foam current collectors exhibit outstanding oxygen evolution reaction activity with a remarkably low overpotential of 290 mV at a current density of 60 mA cm−2 and excellent long-term durability.
