Enhanced photochemical properties of S-doped ZnO half-arc mesoporous superstructured nanowires

The photochemical properties of nanomaterials have always been a research focus in the preparation and optoelectronic applications of nanomaterials. In this work, the porous S-doped ZnO nanowires with cigarette shape were firstly fabricated by direct reaction of zinc foil in aqueous solution of sodium hyposulfite at constant temperature (65 °C). It can be determined that the as-synthesized nanomaterial is elemental S-doped ZnO nanowire with a half-arc mesoporous superstructure characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersion spectroscopy (EDX). Further, through the characterization of photochemical properties, an enhanced photochemical property was observed, indicating the S-doped ZnO nanowire with half-arc mesoporous superstructur have potential applications in dye sensitized photoelectrochemical cells, gas sensors, biosensors, optoelectronic devices, and so on.
