Control to synthesize Bi2S3 nanowires by a simple inorganic-surfactant-assisted solvothermal process

摘要

The large-scale synthesis of uniform Bi_2S_3 nanowires has been successfully synthesized by a solvothermal method adopting an inorganic-surfactant (BiCl_4~--CTA+) lamellar structure as precursor. X-ray diffraction (XRD), hish-resolution transmission electron microscopy (HRTEM), and electron diffraction (ED) results show that the as-synthesized samples are orthorhombic-structured B12S3 single-crystal nanowires. The morphologies and structure of the 61283 nanowires have been characterized using transmission electron microscopy (TEM). In addition, studies of nanowire growth as a function of growth time have shown that nanowire length is directly proportional to growth time. The efficient method can be used to synthesize other III-VI sulfides. The growth mechanism was also discussed in our paper.
