Abstract
In the present study, novel nanocomposites based on carbon electro-graphite modified with titanium dioxide (TiO2) nanoparticles were prepared by a sol-gel method and used as a strong nano photocatalyst to increase the removal efficiency of Furfural from petrochemical saline solutions. The structural properties of the prepared nanocomposite EG@TiO2 were fully characterized by different microscopic and spectroscopic analyses, such as SEM, TEM, XRD, FT-IR, BET, EDS, Raman and GC-MS. Under optimal conditions, the synthesized nanocomposite at acidic pHs increased the oxidation process efficiency of furfural by more than 99.5% in the presence of 50 mg/L of the pollutant, and the oxidation process was completed with the SPEK method in less than 3 h. Furthermore, the XRD results demonstrated that the formed layer at pH = 4 on the electrode surface had more crystallinity than that deposited at pH =8. Therefore, the obtained results for real samples showed that the prepared electrode at pH = 4 increased the Furfural oxidation efficiency and reduced the reaction time.
