The shape of it : A series of anatase TiO 2 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).
