Abstract

Ni_xWO_2.72 nanorods (NRs) are synthesized by a one-pot reaction of Ni(acac)₂ and WCl₄. In the rod structure, Ni(II) intercalates in the defective perovskite-type WO_2.72 and is stabilized. The Ni_xWO_2.72 NRs show the x-dependent electrocatalysis for the oxygen evolution reaction (OER) in 0.1 M KOH with Ni_0.78WO_2.72 being the most efficient, even outperforming the commercial Ir-catalyst. The synthesis is not limited to Ni_xWO_2.72 but can be extended to M_xWO_2.72 (M = Co, Fe) as well, providing a new class of oxide-based catalysts for efficient OER and other energy conversion reactions.
