Synthesis and Characteristics of Nano Silver Zirconium Phosphate for Antibacterial Material Application

   We have successfully synthesized the antibacterial nanomaterial silver zirconium phosphate (AgZrP) via a precipitation method combined with ion exchange. The X-ray diffraction pattern of the AgZrP hot lattice at 900 °C for 2 h revealed a single-phase structure belonging to the cubic space group (hexagonal). The morphological properties and chemical composition were comprehensively analyzed using transmission electron microscopy and energy-dispersive spectroscopy. Simultaneously, surface bond vibration modes were analyzed via infrared spectroscopy. The study facilitated the determination of key technological parameters for the synthesis of AgZrP antibacterial nanopowder, including temperature, precursor concentration, and calcination time. The resulting powder exhibited a size of about 50 nm and demonstrated 5–6 times higher antibacterial efficacy against Escherichia coli compared with silver nanomaterials (with an antibacterial circle diameter reaching 32 mm at a powder concentration of 100 ppm). The AgZrP nanopowder product demonstrates significant potential for use as an antibacterial material in civilian applications.
