Considering the significant influence of ammonia on food,chemical industry and energy,the effective activation of inert N2 production of ammonia plays an important role in modern society.Introducing defects into the crystal structure to regu-late the chemical and physical properties of materials is an effective strategy to improve the electrocatalytic performance of ma-terials.The Ar+ plasma bombardment strategy was used to generate abundant oxygen defects on WO3 nanowire arrays（V-WO3）. The electrocatalytic activation of N≡N bond by V-WO3 nanowire arrays was used to achieve efficient direct ammonia syn-thesis under environmental conditions.X-ray photoelectron spectroscopy（XPS） of oxygen element showed that V-WO3 catalyst was rich in oxygen defects,which led to the efficient electrocatalytic conversion of N2 to NH3.
