This project will address the synthesis of hybrid structures composed of oxides (TiO2, ZnO, WO3, SnO2 and CuO) and metal nanoparticles (Ag, Au, Pt and Pd) displaying controlled shapes, structures, and compositions followed by their applications in catalysis and photocatalysis. We will first focus on the development of synthetic routes of various metal oxides by employing facile strategies and eco-friendly reagents. The obtained materials will be employed as seeds for the deposition of metallic nanoparticles to generate metal oxides-metal particles hybrids in order to improve their photocatalytic properties and catalytic applications, based, for example, the concept of SPR (Surface Plasmon Resonance) of certain metals used in this work (Ag and Au). Thus, in the second part of this work, he catalytic and photocatalytic properties of the synthesized materials will be evaluated and correlated them with the physical-chemical parameters that define the material. It is expected that the obtained results may inspire the development of hybrid materials composed of metal oxides and metal nanoparticles having optimized catalytic, photocatalytic, and electrochemical properties.
