Synthesis and characterization of TiO₂/graphene oxide nanocomposite

Abstract

TiO₂–graphene oxide (TiO₂/GO)-nanocomposite was synthesized by the thermal hydrolysis method. The solution processibility of graphene oxide offers a practical route to carbon-based composites, samples were portrayed by X-ray diffraction, UV–visible absorption spectroscopy, scanning electron microscopy, transmission electron microscopy, and fourier transformed infrared spectroscopy. Phase formation of the TiO₂/GO composite was inspected with powder X-ray diffraction (XRD), the typical surface morphology was done by using scanning electron microscopy (SEM) and the high-resolution transmission electron microscopy (HR-TEM). The different functional groups were perceived by using FT-IR and raman spectroscopy. The optical properties were contemplated using optical ingestion and photoluminescence (PL) spectra. The conductivity and dielectric properties were examined in the different frequencies and the different temperatures. The outcomes demonstrated that the dielectric consistent and the dielectric loss were frequency and temperature dependent. The AC conductivity at various temperatures demonstrated thermal conduction. Furthermore, the electrical conductivity of TiO₂/GO composite was investigated utilizing current density (J)- volteage (V) measurements. In this presentation, we clarify the underlying mechanisms of TiO₂/GO-nanocomposite alignment and itself has significant potentiality as an optical and electrical response.
