Abstract
Polymer nanocomposites based on wide band gap metal oxide nanoparticles are promised functional nanomaterials in many potential applications due to their facile processability. One of their most potential applications is its capability of utilization
in the field of photocatalytic oxidation technology. This thesis was carried out to study some of physical properties of PANI nanocomposites loaded with Co-doped ZnO nanorods to explore their photocatalytic performance. The molar ratio of Co (CH3COO)2 4H2O : Zn(CH3COO)2.H2O was varied from 0:100 to 7:100. Both of the microstructure characterization and UV–visible absorption measurement of the synthesized undoped and Co-doped ZnO nanorods were confirmed the formation of wurtzite ZnO nanostructured crystals without changes in the host structure. The addition of the Co ions into the host ZnO matrix by substitution of the Zn sites was confirmed from microstructure studies. The effect of introducing the Co-doped ZnO nanorods into PANI matrix on structural, surface morphology and electrical properties of the investigated nanocomposites had been studied. For this purpose, the characterization of the fabricated nanocomposites were examined using X-ray diffraction (XRD), Fourier transform infrared (FTIR), high resolution transmission electron microscopy (HR-TEM), and four probe DC electrical conductivity. Furthermore, the dye removal efficiency of fabricated PANI/Co-doped ZnO nanocomposites was examined using UV irradiation to treat different wastewater contaminated with two dyes (Methylene Blue and Procion Blue) as model pollutants and the various photocatalytic parameters were examined. The usage of nanocomposite with the lowest Co concentration as photocatalyst led to oxidize almost 100% of Procion Blue dye in wastewater with initial loading of 10 ppm. Whereas, for Methylene Blue wastewater (10 ppm initial concentration) the oxidation rate reached to only 84% with using such nanocomposite under circulation flow rate of 147 mL/min.
