- Resumen
This PhD Thesis has investigated the development of heterogeneous MOF- type photocatalysts with UiO-66 and MIL-125 topology to obtain solar fuels from water and CO2. Initially, the introduction has reviewed the current state of the art on the use of fossil fuels, renewable energies and solar fuels as energy carriers. In this section, emphasis has been placed on photocatalysis processes based on inorganic semiconductors and MOFs to obtain solar fuels. The results of the thesis indicate that the MOF-type material UiO-66(Zr)-NH2 is a more efficient photocatalyst than the analogues UiO-66(Zr)-X (X: H or NO2) or the titanium MOF MIL-125(Ti)-NH2 for obtaining H2 from the mixtures of water and glycerol. On the other hand, the possibility of developing UiO-66(Zr)-X (X: NH2 or NO2) materials with structural defects introduced with AA or TFA as modulators and presenting enhanced photocatalytic activities and photoinduced charge separation efficiencies for the generation of H2 from water and/or CH3OH mixtures has been demonstrated. This Thesis has also demonstrated the importance of the 2-nitroterephthalate ligand in the preparation of mono- or bimetallic Zr(IV) and Zr(IV)/Ti(IV) active photocatalysts with UiO-66 topology with respect to the analogues prepared with the 2-aminoterephthalate ligand. The RuOx@UiO-66(Zr/Ti)-NO2 material showed the highest activity compared to RuOx@UiO-66(Zr/Ti)-NO2 material.
