Synthesis of Ag-doped TiO2 nanoparticles coated with carbon nanotubes by the sol–gel method and their antibacterial activities
Source abstract
Abstract
In this study, raw single-walled carbon nanotubes (SWCNTs) and multiwalled carbon nanotubes (MWCNTs) were chemically treated with sulfuric acid (H2SO4) and nitric acid (HNO3) in a ratio (3:1). These carbon nanotubes (CNTs) have been coated with Ag-doped TiO2 nanoparticles (NPs) by using the sol–gel method. All samples have been studied by X-ray diffraction (XRD), Fourier transform-infrared (FTIR) spectroscopy, UV–vis spectroscopy, field-emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), and zeta potential analyzer. X-ray diffraction analysis revealed that the polycrystalline structure of silver (Ag) embedded with anatase titanium (TiO2) nanoparticles, while SWCNTs and MWCNTs were verified by EDS spectra due to covering of the (002) peak of carbon nanotubes (CNTs) by the (101) diffraction peak of the TiO2. The FTIR results confirmed the formation of oxygen functional groups onto the SWCNTs and MWCNTs. FESEM results indicated that TiO2/Ag nanoparticles (NPs) successfully loaded onto SWCNTs and MWCNTs. UV–vis absorbance results show a decrease in the energy band gap of MWCNTs-Ag/TiO2 and SWCNTs-Ag/TiO2 in comparison with pure TiO2. Antibacterial activities of nanocomposite samples against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were evaluated by an international recognized test (ASTM E2149). The results showed that nanocomposite samples have a strong bacterial inhibition against E. coli and S. aureus. Gram-negative bacteria appeared to be more resistant to nanocomposite materials than Gram-positive bacteria under illumination by UV light.
