On the synergistic effect of hydrohalic acids in the shape-controlled synthesis of anatase TiO2 single crystals†
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
