Abstract Hydrogen is an emerging fuel, since compared to the conventional fuels, it is environmentally friendly, due to it is based on water splitting. A photocatalytic system is necessary for hydrogen generation from water, which simulates photosynthesis, i.e. there is a photosensitizer, which collects the sunlight, and a catalyst that achieves the hydrogen cation reduction in a molecular hydrogen. The motivation for the present bachelor thesis is based on a previous study, in which titanium dioxide was connected via a covalent bond with metallized porphyrin platinum (Pt) and palladium (Pd) moieties, resulted in a large - scale hydrogen production. This bachelor thesis demonstrates my attempts for the photocatalytic hydrogen generation from graphene oxide covalently linked with platinum and palladium metallized porphyrin moieties. The final product was thoroughly characterized by FT - IR, UV - Vis and PL spectroscopies, X - ray diffraction ( XRD ) while hydrogen production measurements were done in the respective photocatalytic system used.
