Single crystal MoO_3 nanowires were produced using the electrospinning technique.High resolution transmission electron microscopy (HRTEM) revealed that the 1-D nanostructures are 10nm in diameter,on the order of 1μm～2μm in length, and have an orthorhombic structure.It has been demonstrated that a nano-network of MoO_3 nanowires exhibits higher sensitivity and an n-type response to NH_3 as compared to the response of a traditional sol-gel sensor.The structure,crystallinity, and sensoric nature of these single-step processed nanowires are discussed.
