Abstract
In this study, the photocatalytic activity of g-C3N4/Fe3O4/ZnO, g-C3N4/Fe3O4, and g-C3N4 catalysts when exposed to visible light was thoroughly examined. We deliberately take advantage of visible light potential to create electron-hole (e/h+) pairs with exceptional lifetimes. The g-C3N4/Fe3O4/ZnO nanocomposite stands out among the tested catalysts as the undisputed champion thanks to its excellent degrading efficiency. This remarkable result is due to the formation of an interface between g-C3N4 and ZnO, which increases the response to visible light and makes it easier to separate photo-induced electrons and holes, completely. Furthermore, the nanocomposite including Fe3O4 phase addressed the challenge of catalyst recovery and magnetic separation from the solution.
