Synthesis, Spectroscopic Characterization, Photocatalytic And Anti-Bacterial Activities Of Transition Metal Complexes Of Flavonol Base Ligand

Visible light active TiO2 nanoparticles modified with Chloro flavonol base - copper complex (Cu-CLF-TiO2) has been prepared by chemical impregnation route. The optical properties, phase structures and morphologies of the as-prepared nanoparticles were characterized using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction(XRD). Compared to bare TiO2, surface modified photocatalysts (Cu-CLF-TiO2) showed are shifted in the visible region. The photocatalytic activity was monitored in the degradation of Methylene Blue (MB) dye and the results revealed that Cu-CLF-TiO2 showed best photocatalytic activity than TiO2. The superior photocatalytic activity of Cu-CLF-TiO2 could be attributed to the effective electron-hole separation by the surface modifiers. The effect of photocatalyst amount, initial dye concentration and Kinetic studies on the photocatalytic activity was explained in detail. Furthermore, the antifungal activity and their usability of Cu-CLF-TiO2 were tested.
