ABSTRACT
A coral-like ZnO/C-ZnFe2O4 (Z/C-ZFO) photocatalyst was synthesized by simulating the structural characteristics of coral since its structure is conducive to capture and absorption light. The synthesis process involves a two-step process. First, flowerlike hierarchical precursors were through hydrothermal self-assembled route. Next, thermally annealed in nitrogen atmosphere after doping with zinc source. In addition forming heterojunctions that enhance photocatalytic properties, nanostructures endowed Z/C-ZFO significant light-harvesting efficiency. Finally, used for antibacterial applications against Escherichia coli Staphylococcus aureus bacteria. results showed optimized sterilization efficiencies toward E. S. bacteria 99.4 98.0%, respectively, combined excellent cycling stability. method designing synthesizing structures this study may also be extended other optical materials.
