Synthesis of copper oxide nanoneedles over graphene oxide by sonochemical

The sonochemical process is a low-cost synthesis technique that can be employed to enhance or modify chemical reactions, resulting in the formation of diverse materials. Nanomaterials like copper oxide and graphene oxide (GO) have had a significant impact on the world due to their plethora of applications. In this study, copper nanoneedles were synthesized using sonochemical, incorporating CuCl₂, NaOH, and an addition of GO as initial materials. We used SEM and TEM to examine the sample, and this confirmed the needle’s size of 10 nm. The X-ray diffraction patterns reveal a formation of Cu(OH)₂. The elemental mapping confirms the presence of Cu and O and their homogeneous distribution within the Cu(OH)₂ nanoneedles. We utilize point defects in GO as they possess the ability to act as binding traps for Cu clusters, thereby enhancing the strength of the interaction and generating Cu(OH)₂ nanoneedles by a low-cost method like the sonochemical synthesis.
