Synthesis of Biocompatible ZnO/β-CD Nanocomposite and Photocatalytic Degradation Study with Methylene Blue Dye
Article history: Received 20 March 2019 Accepted 29 April 2019 Available online 08 June 2019 In this present work zinc oxide/ β-cyclodextrin nanocomposite was successfully synthesized by a simple precipitation method using zinc nitrate hexa hydrate and sodium carbonate as precursors. The prepared ZnO nanoparticles were mixed with β-cyclodextrin solution under proper proportions and formed nanocomposite then annealed at 150 C for 2 h. The prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UVvisible spectroscopy and AFM. The XRD results indicate that the ZnO crystal has a hexagonal wurtzite structure. The optical properties of the samples are investigated by measuring the UV-VIS absorption at room temperature. FTIR results prove the functional groups present. Photocatalytic degradation of methylene blue (MB) dye was studied using the synthesized nanocomposites applied as photocatalyst.
