Main Article Content
Abstract
INTRODUCTION: Copper bismuthate nanoparticles have garnered significant attention in recent years due to their unique properties and their potential applications in various fields, particularly in electrochemical sensing. These nanoparticles possess a unique combination of properties derived from the synergistic effects of copper and bismuth, making them highly desirable for the development of advanced sensing devices. The synthesis of copper bismuthate nanoparticles involves the controlled formation of nanoscale particles with specific properties and structures. various synthetic methods have been explored, including chemical precipitation, solvothermal synthesis. hydrothermal synthesis. and template.
assisted methods.
Aim: Aim of the study is to synthesize copper bismuthate nanoparticles and investigate their potential applications in electrochemical sensing.
Materials and method: 3.314 grams of bismuthe nitrate was taken in 30 mol of distilled water and was kept for stirring up to 20 minutes. Later 0.8283 grams of copper nitrate was added in 30 ml of distilled water. The solution was maintained a PH 12 by addition of sodium hydroxide, and kept in hydrothermal reactor for 180c for 12 hrs centrifuged and dried at 80c for 8 hrs.
Result: Characterization of the nanoparticle sample was conducted using EDX spectrum analysis and XRD analysis from which data confirming the formation of copper bismuth oxide nanoparticles. The electrochemical sensing capacity of the nanoparticle was analyzed using cyclic voltammetry in comparison to bare carbon electrode. The results show a significant amount of redox activity of hydroquinone at the corresponding applied voltages.
Conclusion: The Synthesised copper bismuth oxide was modified on the surface of the electrode in order to sense the hydroquinone through the electrochemical method.
