AI Article Synopsis

  • Researchers developed a new material called SiO@TiO that has a raspberry-like structure, aimed at lowering the band gap of titania using functionalized graphene oxide as support.
  • Various analytical techniques, including FTIR, XRD, SEM, TEM, and HR-TEM, were used to characterize the material.
  • The band gap was analyzed through UV-Vis absorption spectra and calculated using the Kubelka-Munk equation, accompanied by a theoretical study on the interaction between the components.

Article Abstract

A raspberry-like SiO@TiO new material supported on functionalized graphene oxide was prepared to reduce titania's band gap value. The material was characterized through different analytical methods such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HR-TEM). The band gap value was studied via UV-Vis absorption spectra and determined through the Kubelka-Munk equation. A theoretical study was also carried out to analyze the interaction between the species.
