Abstract
The unique features and prospective applications of Co3O4 nanoparticles to address environmental concerns have attracted significant interest. As a way to produce Co3O4 nanoparticles efficiently, the solution combustion technique is the main emphasis of this study, which also explores the synthesis, characterization, and many applications of these particles. Co3O4 nanoparticles are an attractive choice for energy storage, sensitive sensors, environmental remediation, and catalysis due to their remarkable features, which include their immense surface area, porosity, density, and magnetic properties. Moreover, Co3O4 nanoparticles show potential characteristics in porosity, electrical performance and environmental remediation such as sensitive sensors and water treatment using XRD, SEM, TEM, XPS and BET instruments. Using Co3O4 nanoparticles in smart technology devices offers a different way to accomplish sustainable development objectives like reducing air pollution, slowing down global warming, and water treatment. The comprehensive overview provided by this review highlights the necessity of further research and investigation to fully realize Co3O4 nanoparticles' potential in addressing serious environmental challenges. Keywords: Co3O4 nanoparticles, solution combustion, porosity, sensitive sensors, environmental remediation.
