A ternary nanocomposite material based on TiO 2 , graphene oxide and core-shell nanostructures of Ag/TiO2 composition was obtained by a two-step hydrothermal method. The formation of a dual TiO2-GO nanocomposite was confirmed by Raman spectroscopy data, where the nanocomposite spec- tra contain peaks characteristic of both TiO 2 and graphene oxide. Studies of electrophysical character- istics have shown that the addition of plasmon nanoparticles leads to an improvement in the charge-transfer characteristics of the synthesized material. This is due to the fact that the charge transfer resistance of a ternary nanocomposite material TiO2-GO-Ag is noticeably lower than for pure TiO 2 ( 13 times) and TiO2-GO nanocomposite ( 3 times). In addition, the prescence of Ag/TiO2 core-shell nanostructures in the TiO2-GO nanocomposite material leads to an increase in the efficiency of conversion of incident light into photocurrent, which will be resulted in the growth of photocatalytic activity of synthesized materials.
