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 0.1 M KOH with Ni_(0.78)WO_(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.
