Room Temperature Synthesis of Nanostructured ZnO: Active Visible Photocatalyst in the Degradation of Methylene Blue

Nanostructured ZnO was prepared using a facile solution-phase method at room temperature without need to calcination. Oxidation of zinc sulfate by sodium hypochlorite in the presence polyethylene glycol (PEG) and hydroxide (NaOH) gave pure nanostructured oxide (ZnO-NPs). The structure physicochemical properties material were determined X-ray powder diffraction (XRD), Fourier-transform infrared spectroscopy (IR), Energy Dispersive Spectroscopy (EDS), Scanning Electron Microscopy (SEM), Transmission (TEM), UV–Vis diffuse reflectance their optical Properties. particles successfully distributed two-dimensional sheet with nanometric thickness random distribution. activity evaluated for photocatalytic degradation methylene blue (MB) study experimental conditions such as effect mass catalyst, initial concentration dye volume oxidizing agent. kinetics reaction follow pseudo-first order.
