Treatment of Wastewater from Methylene Blue Dye and E. Coli Bacteria by High-Performance FeO/rGO/TiO Nanocatalyst.

Photocatalysis-based technology has insight into decreasing the disadvantages of traditional approaches and has been identified as an appropriate way to eliminate dyes and bacteria from wastewater. In this work, FeO/rGO/TiO photocatalyst material was synthesized by a simple and fast hydrothermal method. The photocatalyst process results showed that FeO/rGO/TiO nanocomposite degraded methylene blue dye completely in 4 min. Also, FeO/rGO/TiO nanocomposite was very efficient (4.92 log reduction value) for E. Coli bacteria inactivation in 60 min photocatalyst process. The superparamagnetic behavior of FeO/rGO/TiO nanocomposite was investigated by VSM analysis and magnetization saturation was obtained at about 38.46 emu/g which gives simple and fast separation from media to FeO/rGO/TiO nanocatalyst. The structural and morphology properties of FeO/rGO/TiO nanocomposite were studied by XRD, Raman, FT-IR, EDS, FESEM, and TEM analysis. The obtained results confirmed that FeO/rGO/TiO nanocomposite is an efficient nanocatalyst for the treatment of MB dye and E. Coli. Bacteria from water, simultaneously.
