title: Visible light photoactivity from a bonding assembly of titanium oxide nanocrystals.
abstract: TiO(2) nanocrystals are assembled together by interfacial Ti-Ti electronic bonding. Such nanocrystal assemblies have a narrower band gap, greatly enhanced visible light absorption, and solar photocatalysis compared with individual nanocrystals.
