Abstract
This work uses the sonochemical method to represent synthesized cobalt oxide nanoparticles (Co3O4) and analysed using different techniques. The X-ray diffraction analysis (XRD) and Fourier-transform infrared spectroscopy (FTIR) examinations of the synthesized nanoparticles confirmed their cubic structure and average crystallite size of 21.3 nm. The spherical surface shape and presence of components with a particle size of 25.3 nm were revealed. Scanning probe microscopy (SPM) methods analysed the Co3O4 coated plates' surface characteristics, including roughness and topographical ideas. An aqueous electrolyte medium (6 M KOH) was used to investigate the electrochemical corrosion behaviour of Co3O4-coated plates. According to the Tafel plot, coating Zn plates with a high surface area and mesoporous Co3O4 in KOH electrolytes greatly reduced the corrosion of the plates. The coated plates are thermally treated up to 600°. The temperature-dependent anticorrosive properties of Co3O4 NPs are evaluated. [ABSTRACT FROM AUTHOR]
