Preparation and Characterization of Zno Doped Cts/Peg-Ag Nano-Composite for Impacting Photocatalytic Response
An investigation on ZnO-doped (x = 0, 0.03, 0.06, and 0.09) Cts/PEG-Ag nanomaterials have been synthesized by reduction method at 80°C was reported. To study the structural, morphological, particles size, stability, and optical properties of the samples by X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy dispersive spectroscopic (EDS) analysis, Fourier transform infrared (FTIR) spectroscopy and UV-visible spectroscopy have been studied. The XRD spectrum shows that all the samples are facing center cubic (fcc) structure. The presence of functional groups and chemical bonding is confirmed by FT-IR. The ultraviolet-visible measurement showed an increasing ZnO content, probably due 116to an increase in the lattice parameters. ZnO doped Cts/PEG-Ag nano-composite showed excellent photocatalytic behavior and the underlying mechanical properties. Hence ZnO doped Cts/PEG-Ag nanocomposite has potential application as photocatalyst and can also be used as a water purifier. The DLS results show that the nanocomposites have a favorable compatibility and stability. In application study, it is proved that this has photoreduction (exposure to sunlight) leaded to the potential aggregation of silver nanoparticles: metal ions that were released tended to aggregate at the surface of the material. Photocatalytic activity of Cts/PEG/Ag and 0.09M ZnO doped Cts/PEG-Ag nanocomposite was examined by studying the photodegradation of the product under natural sunlight irradiation and the results clearly showed that ZnO doped Cts/PEG/Ag sample exhibited higher activity than Cts/PEG-Ag.
