摘要：

The present study has focused the synthesis of Fe3O4-ZnO and citric acid/glycine-modified Fe3O4-ZnO nanocomposites by co-precipitation followed by sol-gel method. The structural elucidation of modified Fe3O4-ZnO nanocomposites has revealed by XRD, SEM-EDX, FT-IR, and UV-Vis spectrophotometer studies. The analytical studies have revealed that the average crystallite size found to be 10-47 nm with spherical shape on smooth surface. The band gap energy range has found to be 1.52 to 3.12 eV. The catalytic activity of synthesized nanocomposites has undergone the oxidation of benzaldehyde, and the antibacterial activity has done using gram-negative bacteriaEscherichia coli. The experimental results have concluded that the citric acid-iron oxide nanocomposite has showed the higher yield in oxidation reaction and the citric acid-iron oxide nanocomposite has showed higher efficiency in antibacterial activity comparatively.
