Abstract
SUMMARY
Nanotechnology is increasingly attracting worldwide attention, where the nanomaterials have unique structure and properties.
The experimental procedures and instrumentation as well as methods of analyses used in this study were presented.
The thesis consists of four chapters:
Chapter I: gives a general introduction including theoretical background about hydrazone ligand, transition metal complexes containing chromone and/or isatin moiety Furthermore, the importance of zeolite as a host material for complexation was demonstrated. Biomedical and catalytic applications were presented. The literature survey concerning the thesis topics was also given.
Chapter II demonstrates different experimental techniques, preparation a hydrazone ligand and its complexes of Cu(II), Ni(II), Co(II), Zn(II), Cd(II) and UO2(IV) and data analysis methods used in this thesis.
Chapter III aims to characterization the hydrazone ligand and its complexes Cu(II), Ni(II), Co(II), Zn(II), Cd(II) and UO2(VI) with crystalline or amorphous structures. The results obtained in this chapter are summarized as follows:
1- The changes in the spectroscopic data of the hydrazone ligand upon coordination indicate that the ligand behaves as neutral tridentate ligand manner with ONO donor sites through the γ-pyrone oxygen, azomethine nitrogen and oxygen of the isatin moiety.
2- The spectroscopic data and magnetic moment measurements revealed that metal complexes exhibited octahedral geometry except dioxouranium(IV) complex in which the metal ion is hepta-coordinated. The metal complexes have 1:1 metal-to-ligand stoichiometry. All complexes are neutral and have lower molar conductivity. The lower absorbance and magnetic moment values of the MII-complexes/NaY than pure MII-complexes are weak due to their low concentrations in zeolite matrix
3- XRD analysis showed that the pure M(II)-complexes are not perfectly crystalline with average crystallite sizes ranged between 47 and 29 nm.
4- The XRD pattern of the M(II)-complexes/NaY zeolite nanohybrid material are similar to that of pure zeolite Y, apart from slight changes in the peak intensities, which indicated that the M(II)-complexes are highly dispersed into zeolite cavities and confirm that the zeolite framework did not undergo any significant structural changes during encapsulation.
5- Transmission electron microscope (TEM) analysis showed that Cu(II) and Ni(II) complexes have rod shape morphology while Co(II) complex has sheets like shape. These complexes have the same shapes inside zeolite cavities.
6- The encapsulation of Cu(II) and Co(II) complexes in zeolite cavities reduced the surface area and the pore volume for CuII and CoII –complexes/NaY equal to 0.06 and 0.059 nm, respectively. This may lead to consider zeolite Y as a suitable host for both metal ions and can facilitate complexation inside zeolite cavity.
7- The prepared ligand, its pure M(II)-complexes and M(II)-complexes/NaY were applied as antimicrobial against microorganisms. CuII-complex/NaY is the most active one in comparison with the other complexes.
8- The Ligand, its pure MII-complexes and immibolized MII-complexes/NaY zeolite (MII=CuII and ZnII) were tested for their in vitro cytotoxicity against liver Carcinoma cell line (HepG2). The highest antimicrobial and antitumor activity was given by CuII-complex immibolized into zeolite.
9- The toxicity test on mice in comparison with cisplatin showed that Cu(II) complex immibolized into zeolite Y has lower toxicity (IC50=1245 μg) than the standard cis-platin.
10- The pure complexes and nanocomplexes immibolized into zeolite have been studied in different green chemistry applications as a catalytic material for degradation of textile dyes (methylene blue (MB) and remazole red (RR)) and drug (oxo-fluxacine (OF)) and environmental applications such as industrial wastewater treatment. from COD analysis, the studied dyes are completely mineralized after 6h only. Moreover, The mineralization efficiency of industrial wastewater using highly active nanoparticles (MII-complex/NaY (MII = CuII, CoII)) in dark reached to 88% and 92% respectively, after 6h of reaction.
11- The pure complexes tested as dye sensitizer in dye synthetized solar cell DSSC. The DSSCs with CuII, NiII, CoII, CdII and ZnII-complexes loaded TiO2 thin film electrodes show a conversion efficiency of 0.053%, 0.089%, 0.068%, 0.092% and 0.017 %, respectively.
12- The absorption coefficient of NiII-complex has the highest molar absorption coefficient relative to other nanocomplexes.
13- The CdII and NiII-complex showed the maximum current efficiency, but ZnII-complex showed the least current efficiency.
