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 (including rutile TiO₂ nanowires on fluorine-doped tin oxide substrate, anatase TiO₂ nanorods/nanoflakes on fluorine-doped tin oxide substrate, and anatase TiO₂ nanowires on titanium foil) for improving the performance of TiO₂ in dye-sensitized solar cells (DSSCs), photoelectrochemical cells (PEC) and photocatalysis.

Prof.Bin Liu received his B.Eng. (2002) and M.Eng. (2004) in chemical engineering from the National University of Singapore and Ph.D. in chemical engineering from University of Minnesota (2011). He also worked as a postdoctoral researcher (2011-2012) in the Department of Chemistry at University of California, Berkeley. He is currently an Assistant Professor in School of Chemical and Biomedical Engineering at Nanyang Technological University. Bin has extensive experience in synthesis of nanostructured materials and has been working on nanostructured materials for energy conversion and energy storage for more than 10 years
