Abstract
While most anatase TiO2 crystals reported were in the form of nanoparticle, herein the tuneable and controlled (0 1 0)-faceted anatase phase were grown directly onto a conductive substrate. F− ions provided by addition of ammonium hexafluorotitanate (AHFT) play a synergistic effect in the crystals phase changed from rutile to anatase during crystal growth with low-index facets. The morphological transformation from vertically-aligned rutile-nanorods to highly crystalline anatase-nanosheets bounded with the most significant percentage of (0 0 1) facets with the effect of F− ions. At higher concentration of AHFT dominate the (0 1 0)-faceted anatase TiO2 with suppression of (0 0 1) facets of nanosheets (side length of 1.4 µm), which can suppress the charge recombination for an electron transport layer in solar cell applications, and thus, efficient charge transportation can be achieved compared to nanoparticles.
