Abstract

Through the controlled removal of surfactant from the presynthesized mesolamellar precursor (WO-L) at elevated temperature, tungsten oxide nanowires with diameters ranging from 10 to 50 nm and lengths up to several micrometers were obtained on a large scale. The structure, morphology, and composition of the nanowires were characterized by the XRD, TEM, HRTEM, EDX, and Raman spectra.

摘要

通过在高温下从预合成的介观层状前驱体（WO-L）中可控地去除表面活性剂，大规模制备出了直径范围为10至50纳米、长度可达几微米的氧化钨纳米线。利用X射线衍射（XRD）、透射电子显微镜（TEM）、高分辨率透射电子显微镜（HRTEM）、能谱仪（EDX）和拉曼光谱对纳米线的结构、形态和组成进行了表征。
