摘要: Thermal and chemical (antibacterial) properties of Ag nanoparticles deposited on the surface SiO2 were studied to know possibility applying them as antibacterial materials. To prevent aggregation increase their abilities, hybrid structures Ag−SiO2 nanocomposites synthesized by one-pot sol−gel method. The thermal behavior investigated with X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission (TEM). examined minimum inhibitory concentration (MIC). property shows no significant change below Tammann temperature (e.g., 293 573 K); however, it was decreased upon increasing above (673 − 1073 K) because growth SiO2.
