Abstract

PbTiO3 nanocrystals were synthesized by a two-step hydrothermal method. The effect of Pb/Ti molar ratio (0.50 – 1.50) in the first-step precursors on morphologies of PbTiO3 nanocrystals were investigated. The single-phase PbTiO3 nanocrystals were obtained at Pb/Ti molar ratio of 0.75 – 1.25. By varying the Pb/Ti molar ratio from 0.75 to 1.50, the morphologies of PbTiO3 nanocrystals changed from nanoparticles, to cubic nanocrystals, window-frame-like nanocrystals and nanoplates. The PbTiO3 nanocrystals with cubic and window-frame-like morphologies showed good photocatalytic degradation of methylene blue under the visible-light irradiation.
