Nanosized anatase TiO2 single crystals for enhanced photocatalytic activity

Chem Commun (Camb). 2010 Feb 7;46(5):755-7. doi: 10.1039/b919895d. Epub 2009 Nov 27.

Abstract

Nanosized anatase TiO(2) single crystals with 18% {001} facets have a raised conduction band minimum by 0.1 eV, and exhibit photocatalytic activity both for generating *OH radicals and for splitting water into hydrogen that is markedly superior--by factors of 5.6 and 8.2, respectively--to reference ca. 3 microm anatase TiO(2) with 72% {001} facets.
