Synthesis of nano-micro chestnut TiO2 with rutile nano-pin on the micro-anatase octahedron

Abstract

The solution synthesis of large single crystals of octahedron-like anatase TiO2 is reported, although this novel result is unexpected in the light of reported theoretical calculations. Moreover, systematic control of the crystal growth of rutile nano-pins on the micro-anatase octahedron single crystal results in a nano-micro chestnut-like TiO2 structure.
