Colloidal synthesis of urchin-like Fe doped NiSe2 for efficient oxygen evolution

Abstract

The search for highly efficient non-precious electrocatalysts toward oxygen evolution reaction (OER) is extremely essential for the renewable energy systems. Here, we reported the colloidal synthesis of Fe doped NiSe2, which function as high-performance electrocatalysts for OER in alkaline solution. The NiFeSe catalysts are composed of urchin-like dendrites with highly increase active sites, could provide fast transportation of electrons and electrolytes, and facile release of the evolved O2 bubbles during the OER catalysis. Benefitting from this unique urchin-like structure and strong electron interaction between Fe and Ni, Se, the Ni1.12Fe0.49Se2 catalyst exhibits excellent electrocatalytic activity and high durability toward OER in alkaline solution, with an overpotential of 227 mV at current density of 10 mA/cm2, which is, to the best of our knowledge, higher than most of the reported selenide-based electrocatalysts.
