摘要 |
Titanium dioxide (TiO2) is one of the most widely used semiconductors in photovoltaics and photocatalysis because it is nontoxic, abundant, stable and photoactive. However, the wide bandgap, low electron mobility and short minority carrier diffusion length of TiO2 limit its quantum efficiency in these applications. In this talk, I will present a solution chemical approach for making TiO2 nanostructures (including rutile TiO2 nanowires on fluorine-doped tin oxide substrate, anatase TiO2 nanorods/nanoflakes on fluorine-doped tin oxide substrate, core-shell TiO2 nanowires made of beta-phase core and anatase shell, and C-doped TiO2 mesoporous microspheres) for improving the performance of TiO2 in dye-sensitized solar cells (DSSCs), photoelectrochemical cells (PEC) and photocatalysis. |
