Abstract

Understanding fundamental crystal nucleation and growthmechanismsis critical for producing materials with controlled size and morphologicalfeatures and uncovering structure–function relationships inthese semiconducting oxides. Under hydro-solvothermal conditions,uniform branched and spherulitic TiO2rutile nanostructureswere formed via (101) twins. On the basis of detailed, high-resolutionscanning electron microscopy and transmission electron microscopyanalyses, we propose a mechanism of branched growth and the (101)twin formation via oriented attachment and subsequent transformationfrom anatase to rutile.
