Abstract

Abstract: A microfluidic system was developed for the synthesis of trigonal selenium(t-Se) nanowires, which was composed of a glass microchip coupled with a poly(methyl methacrylate)(PMMA) microchip. In the glass microchip, amorphous selenium(a-Se) colloid was prepared by reducing selenious acid with an excess amount of hydrazine at a temperature of 100 °C. In the coupled PMMA microchip, a-Se was transformed into more stable t-Se seeds via sonication at room temperature. The residence time of the reactants in both microchips was optimized by varying the dimension and length of the microchannel each. The t-Se nanowires were formed by anisotropic growth of selenium crystallite during sonication and aging under the assistance of β-cyclodextrin(β-CD). Various stages of the nanowires’ growth were investigated. The as-synthesized products were characterized by powder X-Ray diffraction(XRD), Raman spectroscopy, scanning electron microscopy(SEM), transmission electron microscopy(TEM) and selected-area electron diffraction(SAED).
