Construction of ZnNiO2/rGO nanocomposites with enhanced photocatalytic performance

Pure ZnNiO2 nanoparticles and a series of (reduced graphene oxide- (rGO)) rGO/ZnNiO2 nancomposites were synthesized through a facile hydrothermal and thermal decomposition method. The rGO/ZnNiO2 nanocomposite was characterized by XRD, FT-IR, Raman, DRS-UV Visible spectroscopy and FE-SEM and HR-TEM instrumental techniques. In a XRD analysis, cubic phase of the crystal system of the ZnNiO2 nanoparticle was observed. The Zn-O and NiO group was confirmed by the FT-IR and Raman spectroscopy examinations. rGO/ZnNiO2 nanocomposite indirect bandgap energy was examined by DRS UV Visible spectroscopy studies, with calculated bandgap energies at 2.1 to 1.75 eV. In this case, (25/75) rGO/ZnNiO2 nanocomposites have higher efficiency because of bandgap energy is too lower. These materials newly designed with using for various ingredients with surfactants and low cost, good stability and excellent optical properties and photocatalytic properties therefore we have developed. We are generally listening carefully to photocatalytic degradation of dye in the occurrence of rGO doped ZnNiO2 catalysts. Besides, synthesized all rGO doped materials are enhanced to the photocatalytic response. Especially, (25/75) rGO/ZnNiO2 nanocomposite was effectively performed to the photocatalytic applications with marvelous stability studies also examined. The pure ZnNiO2 nanomaterial has recorded to the crystallite size at 12.13 nm.
