EFFECT OF MOLARITY ON GROWTH OF NANORODS ON WIRE VIA SONOCHEMICAL METHOD

Abstract

In this work ZnO nanorods were successfully grown sonochemically on several types of wires, (silver (Ag), nickel (Ni), copper (Cu) and tungsten (W)) using zinc nitrate hexahydrate and hexamethylenetetramine (HMT) solution at different molarity without template or surfactant assistance. The SEM morphology showed the nanorods are non- directional as compared to those grown on semiconductor substrate. Nonetheless, XRD indicated that ZnO structure follows the hexagonal wurtzite structure with the preferential growth in the (002) direction. Different densities and sizes of nanorods were observed using different concentrations. This study provides a novel yet efficient approach for the synthesizing of ZnO nanorods.
