Sonochemically Grown 1D ZnO Nanostructures and Their Applications

摘要

Sonochemical growth technique is based upon the chemical effect of ultrasound on chemical reactions. This process is carried out at an ambient atmosphere without the need for a complex experimental set up and additional heating. This method is of significant importance because of it's vital application in various fields. ZnO nanorods were grown on glass substrates without any additional heat or surfactance by sonochemical growth technique. The grown nanostructures were characterized by Raman spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Sonochemically grown ZnO nanorod networks were characterized for their antibacterial properties toward B.subtilis. These structures were also characterized for their CO sensing properties and photovoltaic performances for dye sensitized solar cell (DSSC) application. All material characterization and device performances suggest that sonochemsitry can be utilized as an alternative growth method for 1D ZnO nanostructures.
