Abstract：
The changeover from fossil fuels to renewable energy sources is changing the future energy scenario. New advanced nanomaterials with photoactive properties are necessary to address this challenge. In the field of functional nanostructured materials a particular interest is devoted to TiO2. The unique physicochemical characteristics, biocompatibility, availability and relative low cost have justified the extensive use of this semiconductor. The ability to control the structure of TiO2 in the nanometer scale have opened new opportunities and prospects of technology applications in different fields, in particular for materials for energy and solar fuel applications, either to produce hydrogen or as components of solar cells. Anodic oxidation (AO) of titanium foils represents an attractive route to prepare, at low costs and potentially large size, TiO2 thin films with well-defined and controllable 1D/2D structures in the nanometer scale.
The lecture will discuss sixth cases of utilization of titania nanostructured thin films for the production of renewable H2 and application in the area of solar cells: (1) 1D TiO2 nanostructures preparation by AO as photo-anodes for PEC cells to produce solar fuels, (2) thin titania films and Cu-doped titania catalysts as catalysis for H2 production by photo-reforming and -photo-dehydrogenation, (3) titania thin films with specific nano-roughness as photoactive transparent coatings having self-cleaning and antireflection properties, (4) nano-in-nano titania ordered films for DSSC cells, (5) hedgehog-type TiO2 thin films for advanced solar cells and (5) TiO2 - CNTs nanocomposite films Hydrogen Leak Sensors for Fuel Cell Transportation.
