One-step preparation of RGO/Fe₃O₄-FeVO₄ nanocomposites as highly effective photocatalysts under natural sunlight illumination.

ABSTRACT: The study used a one-step hydrothermal method to prepare Fe₃O₄-FeVO₄ and xRGO/Fe₃O₄-FeVO₄ nanocomposites. XRD, TEM, EDS, XPS, DRS, and PL techniques were used to examine the structurally and morphologically properties of the prepared samples. The XRD results appeared that the Fe₃O₄-FeVO₄ has a triclinic crystal structure. Under hydrothermal treatment, (GO) was effectively reduced to (RGO) as illustrated by XRD and XPS results. UV-Vis analysis revealed that the addition of RGO enhanced the absorption in the visible region and narrowed the band gap energy. The photoactivities of the prepared samples were evaluated by degrading methylene blue (MB), phenol and brilliant green under sunlight illum
