Abstract

Cuboid-like anatase TiO2 single crystals bounded by {001} and {100} facets have been successfully synthesized with HCl as a synergistic capping agent together with HF, under the guidance of theoretical calculations. DFT calculations suggest that the preferred replacement of HCl with HF at (100) as well as its favorable adsorption provide a unique stabilization effect on the formation of cuboid-like anatase TiO2.
