Synthesis of CaO–Ag-NPs @CaCO 3 Nanocomposite via Impregnation of Aqueous Sol Ag-NPs onto Calcined Calcium Oxalate
2019
In this research CaO–Ag-NPs @CaCO3 nanocomposite was prepared by treatment of calcined calcium oxalate [CaO, Ca(OH)2 and CaCO3] with sol of silver nanoparticles (Ag-NPs). Several techniques were used to investigate the structural properties of CaO–Ag-NPs@CaCO3 nanocomposite including FTIR, UV/VIS, XRD, TEM and TGA. XRD and TEM and UV/VIS results showed that silver nanoparticles incorporated with calcium oxide (CaO–Ag-NPs) are incorporated with calcium carbonate (CaO–Ag-NPs@CaCO3). It is confirmed that the CaO–Ag-NPs @CaCO3 nanocomposite showed strong antimicrobial activity against Escherichia coli, and Staphylococcus aurous.
