Removal of Nitrophenols from wastewater by monoclinic CuO/RGO nanocomposite

Abstract

The copper oxide/reduced graphene oxide (CuO/RGO) nanocomposite (NC) was synthesized via simple and green hydrothermal method. The prepared NC was characterized by XRD, SEM, EDS, FTIR and UV-DRS for structural and morphological studies. The experimental results proved that pure nanocomposite is formed by the hydrothermal route. The FTIR spectra of prepared composite reveal the observed three peaks at 600–400 cm−1, confirming the formation of composite is monoclinic CuO. The photocatalytic activity of synthesized NC was tested by degradation of ortho and para nitrophenols (NP) under visible light illumination. The CuO/RGO NC served as visible photo-driven catalyst for degradation of both ortho and para nitrophenols in 120 and 180 min, respectively; this may be due to lower bandgap of CuO nanoparticles in NC by the addition of RGO.
