摘要：

Octahedral titanium(IV) oxide (TiO(2)) crystallites with exposed anatase {101} facets exhibited relatively high photocatalytic activity for oxidative decomposition of organic compounds and low activity for hydrogen evolution in the absence of molecular oxygen, probably due to the characteristics of the anatase {101} surface.
