Abstract

Nanosized anatase TiO₂ 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 μm anatase TiO₂ with 72% {001} facets.
