Abstract

straightforward, easy and low-cost process using cetyltrimethylammonium bromide (CTAB) as a templated sonochemical production  method was used to prepare ZnO nanostructures with the appearance of flowers. The morphological characteristics of ZnO materials  have a more significant impact on variables like the CTAB template and sonochemical reaction time. The advantage of the flower-like  ZnO materials is the more active reaction centre, which improves redox processes and results in outstanding electrochemical attributes like greater specific capacitance, excellent rate capability and better cyclic stability. The specific capacitance of the flower-shaped ZnO  nanostructures (ZnO-2) from the cyclic voltammetric (CV) analysis was found to be 425 F g–1 at a scan rate of 5 mV s–1 and the charge/discharge study renders the specific capacitance is 426 F g–1 at a current density of 1 Ag–1. After 3000 CV cycles at a scan rate  of 100 mV s–1, 89% of the initial capacitance still was retained in the long-term cyclic stability analysis. The distinctive flower-like ZnO  nanostructures can be extended more for supercapacitor device applications.
