Hierarchical Iron-Doped Nickel Diselenide Hollow Spheres for Efficient Oxygen Evolution Electrocatalysis
Source abstract
Abstract
Explorin gearth-abundant oxygen evolution reaction electrocatalysts is attracting tremendous attention but still remains challenging. In this study, we design and synthesize hierarchical iron-doped nickel selenides with hollow structure and tunable composition. Benefiting from the synergistic effects of high specific surface area and optimal heteroatom doping, 5% Fe doped NiSe2 hollow spheres present excellent performances, exhibiting a 10 mA cm–2 current density at the overpotential as low as 231 mV and long-term stability for 20 h at 15 mA cm–2 in the basic medium.
