Solvothermal synthesis of anatase TiO2-graphene oxide nanocomposites and their photocatalytic performance |
| 초록 |
Anatase TiO2-graphene oxide (GO) nanocomposites with different GO loadings were prepared by a solvothermal method. The prepared photocatalysts were characterized by X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), Fourier transform infra-red spectroscopy (FTIR), and photoluminescence spectroscopy (PL). The XRD results confirmed the anatase phase of TiO2 in the composites while the Raman analysis revealed the presence of GO in the nanocomposites. TEM studies indicated the uniform dispersion of TiO2 NPs on the GO surface with slight aggregation. The photocatalytic performance of the prepared nanocomposites was evaluated by the degradation of gaseous benzene under UV light irradiation. Anatase TiO2-GO nanocomposites exhibit better photocatalytic performance than pure TiO2 nanoparticles. The anatase TiO2-GO nanocomposites facilitate the separation of photogenerated charge carriers along with high stability, which ultimately enhance the photocatalytic activity under ultraviolet irradiation. The present study opens up new opportunities for the development of innovative, next generation heterojunction photocatalysts for environmental remediation applications. |
