Facile synthesis and physical properties of magnesium dititanate nanoparticles for antibacterial applications

Abstract

AbstractThe modified aqueous co-precipitation approach was used to successfully manufacture magnesium dititanate (MgTi2O5) nanoparticles. Thermogravimetric analysis/differential scanning calorimetry (TG/DSC) was used to clearly reveal the thermal stability. Moreover, pseudobrookite structure, and surface morphology of MgTi2O5 nanoparticles were determined using X-ray diffraction (XRD), transmission electron microscope (TEM), and Fourier-transform infrared (FT-IR), and scanning electron microscope (SEM) techniques, respectively. The average size of the crystallites calculated by Scherer approach was compared to Williamson-Hall and TEM images results. The optical band gap of MgTi2O5 nanoparticles was found to be 3.81 eV for direct transitions. The effect of temperature on the conductivity of DC electricity was tested between the rages 303–503 K. The data on antibacterial activity showed that MgTi2O5 nanoparticles were antimicrobial and stopped the test microorganisms from growing. These findings revealed that MgTi2O5 will be extensively promising in environmental pollution control and antibacterial research.
