Homogeneous Photocatalytic Hydrogen Production from Water with the Mixed Diimino-Thiolamino Complex of Ni(II)
Summary:
The purpose of this research is to study photocatalytic systems with Nickel (II) complexes. These complexes were synthesized and characterized in the laboratory of Inorganic Chemistry, NKUA by spectroscopic techniques such as visible-ultraviolet spectroscopy (UV-Vis), infrared spectroscopy (FT-IR), and fluorescence.
Therefore, the study of the photocatalytic hydrogen production is presented using systems that contains three components. Fluorescein is used as a photosensitizer. The complexes [Ni(2-aminothiophenol)(1,10-phenanthroline)] and [Ni(2-aminothiophenol)(2,2'bipyridine-4,4'dicarboxylic acid)] as photocatalysts, with electron donors triethanolamine (TEOA) in mixed solvent DMF:H2O. The produced hydrogen is detected by the gas chromatography. The above system has been fully studied to find out conditions. In addition, the mechanism of this system is investigated using visible-ultraviolet as well as fluorescence spectroscopies. Finally, a comparative study of the hydrogen production by abovementioned systems is presented.
