Construction and synthesis of NiCo2O4 nanozyme for enhanced antibacterial performance
Source abstract
Abstract
Abstract Developing effective and low-cost enzyme-like nanomaterials to kill bacteria is vital for human health. Herein, nanorod-assembled NiCo2O4 microspheres were prepared though a facile hydrothermal method, andshowed highly enhanced peroxidase-like activity compared to pure Co3O4 due to its large surface area and abundant active sites. The NiCo2O4 possess the ability to catalyze H2O2 to generate large amounts of •O2−, which can be used for bacteriostatic applications. In particular, the antibacterial system combining the spiky NiCo2O4 particles and a low concentration of H2O2 (100 μM) exhibits an excellent bacteriostatic efficiency against both Escherichia coli (94.44%) and Staphylococcus aureus (93.45%).
