Title: Ni xWO 2.72 nanorods as an efficient electrocatalyst for oxygen evolution reaction

Ni xWO 2.72 nanorods (NRs) are synthesized by a one-pot reaction of Ni(acac) 2 and WCl 4. 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 0.1M KOH with Ni 0.78WO 2.72 being the most efficient, even outperforming the commercial Ir-catalyst. Lastly, 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.
