| Abstract: | The persistent presence of malachite green oxalate (MGO) in industrial effluents poses a significant threat to environment, aquatic life and human health. This study reports the synthesis of ZnO nanorods via a magnetic stirred mechanically assisted thermal decomposition method, with systematic variation in magnetic stirring durations (0, 1, and 4 h) post heat treatment to enhance photocatalytic performance. Comprehensive characterization using XRD, FE-SEM, UV-Vis diffuse reflectance, and photoluminescence spectroscopy confirmed the formation of wurtzite-phase ZnO nanorods. Photocatalytic degradation experiments, conducted under 80 W Hg bulb irradiation, revealed that increasing magnetic stirring duration led to enhanced dye degradation efficiency (4-hour stirred sample heat treated at 300 °C). Magnetic stirring post heat treatment has tremendously increased the rate constant by ~ 64% and 115% for one hour and four hours, respectively with respect to unstirred ZnO. The percentage enhancement of rate constant with unstirred ZnO nanorods is 1.8×103% with respect to photolysis, which further increased to 3.1×103% and 4.1×103% for one hour and four hours, respectively. These results highlight the critical role of magnetic stirring post heat treatment in tailoring the structural and functional properties of ZnO nanorods for effective wastewater treatment applications.
