Background: Antibiotics commonly used to treat bacterial infections in clinical practice can lead to the creation of drug-resistant bacteria, which are more difficult to eradicate. Therefore, there is an urgent need to develop a new antibacterial agent and antibacterial means that will not make bacteria resistant to resistance.

Methods: We synthesized MoO42-/PCN-222 composites using a simple hydrothermal and electrostatic adsorption methods. We characterized the successful synthesis of the material by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). Then we tested the photocatalytic and photothermal properties of the materials, and finally we evaluated the antibacterial properties of the materials against Staphylococcus aureus by the spread plate method.

Results: The results showed that MoO42+/PCN-222 composite had excellent antibacterial properties, and 20MoO42+/PCN-222 could kill 94.05% of Staphylococcus aureus under 660 nm light irradiation for 10 minutes.

Conclusions: In this article, we synthesized MoO42-/PCN-222 composites by a simple hydrothermal and electrostatic bonding method. The material has excellent photocatalytic and photothermal effects, so the composite material has excellent killing effect on S. aureus. We believe this work can provide new insights for the application of PCN-222 based materials.
