Abstract

Single-crystalline tetragonal perovskite PbTiO₃ nanosheets are synthesized via a hydrothermal route assisted by NaNO₃ and KNO₃. Due to the difference in electronegativity, Na⁺ ions fasten on (001) planes, whereas K⁺ ions fasten on (111) planes, resulting in PbTiO₃ nanosheets with dominant (001) or (111) facets, respectively.
