(440b) Improving Electron Transport in TiO2 Electrode Via Nanostructure Engineering

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 work, we present a solution chemical approach for making TiO₂ nanostructures for improving the electron transport in nanostructured TiO₂ electrodes.
