Nanoparticles and nanocrystals of semiconducting oxides constructed from
nanoscale building blocks often possess unique and much improved
properties. Such materials are promising in enabling innovative
technologies for conversion and storage of renewable energies for the
future. With current challenges in climate change and sustainable
development, nanotechnology is especially exciting because it provides
great opportunities for technological advances in areas of solar power,
solar hydrogen production and storage.

This talk highlights the latest developments in oxide nanomaterials such
as titania as photocatalysts. Materials such as layered titania and
single anatase crystals are photoactive materials promising for cheap
and efficient solar cells, hydrogen production from water splitting and
solar detoxification of water and air.  Latest advances in bandgap
engineering of TiO2 for visible light photocatalysis will be highlighted
and discussed.
