Abstract

The sonochemical synthesis involved the dispersion of zinc oxide (ZnO) precursor in a suitable solvent, followed by ultrasonic irradiation to induce chemical reactions and nucleation of ZnO nanoparticles. The resulting nanomaterials exhibited a uniform particle size distribution, which is crucial for their photocatalytic efficiency. ZnO nanoparticles with a uniform particle size of 25 nm were successfully synthesized using a sonochemical route and were employed for the degradation of direct green and fast orange dyes under UV light irradiation. The band gap of the ZnO nanoparticles was determined to be 3.35 eV, indicating its potential as a photocatalyst for dye degradation. The degradation efficiency of the dyes was evaluated by monitoring the change in their  concentration over time. The ZnO nanoparticles demonstrated excellent photocatalytic activity, efficiently degrading both dyes within a relatively short duration. The electrochemical studies further confirmed the potential applicability of the synthesized ZnO nanoparticles in various electrochemical systems. The ZnO electrode that was produced could detect lead in an acidic solution. The ZnO electrode is a promising electrode material for making sensor applications because of its higher electrochemical behaviour. Overall, this research contributes to the development of efficient and environmentally friendly approaches for wastewater treatment and lead sensor.
