Abstract

original image

The shape of it: A series of anatase TiO2 nanocrystals with exposed high-energy {001} facets or high-index {103}, {102} facets and/or low-energy {101} facets were successfully synthesized via a fluorine-free route, and crystal-facet-dependent photodegradation activities were found to follow the sequence of {001}>{102}≈{103}>{101} (see picture; the scale bars are 200 nm).
