Hydrothermal Preparation of Ag/TiO2/GO Nanocomposites with Ammonia-Treated Graphene Oxide for Enhanced Conductivity

In this study, Ag/TiO₂/GO nanocomposites were successfully fabricated by a facile hydrothermal method. Nitrogen-doped GO was prepared using ammonia treatment to improve its conductivity. The Ag/TiO₂/GO nanocomposites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS), zeta potential, and photoluminescence spectroscopy (PL). A homogeneous dispersion of Ag/TiO₂ nanoparticles was shown on the surface of GO. Increasing the nitrogen doping concentration increased hydrophilicity, thereby improving the conductivity of Ag/TiO₂/GO nanocomposites.
