Photoelectrochemistry

Research Areas

The Photoelectrochemical group aims at developing a new class of multicomponent hybrid systems (HNS) composed of a central material (CS), most likely metal oxides semiconductors (TiO₂, α-Fe₂O₃, ZnO, WO₃, BiVO₄, etc.) and carbon based materials with controlled shape and dimensionality (e.g., 1D-nanotubes, 2D-ultrathin films, 3D branched nanoarchitectures, etc.) that will work as highly photocatalytically and electrocatalytically active materials for a broad portfolio of energy and environmental applications including direct splitting of water, photocatalysis, electrocatalysis, dye sensitized solar cells, etc.. The key-approach is represented by the simultaneous and synergistic combination of strategies (nanostructuring, co-catalyst deposition, surface sensitization) that are still very often studied and developed independently. Therefore, the nanostructured CMs are coupled to counterparts with specific functionalities (extended visible light absorption, remarkable efficiency in charge transfer, enhanced carrier mobility) and the effective interaction of the single components will significantly benefit the PEC efficiency of the composite system. The group is very well equipped for a thorough electrochemical, photoelectrochemical, and photocatalytic investigation of the materials and hybrid nanostructures developed.
