Synthesis of Various Shapes of Titanate Nanoparticles via Hydrothermal Reaction

摘要

Various shapes and aspect ratio of titanate nanoparticles have been synthesized via a one-pot synthetic method involving an autoclave system using irregularly shaped anatase nanopowder. The influence of reaction conditions such as raw material concentration, temperature, pressure and reaction time to the particle morphology have been studied systematically. The particles were characterized by FESEM, EDX, TEM, HRTEM and XRD. Ultrahigh aspect ratio titanate particles with the length of up to hundreds of micrometers have been observed. The XRD result shows that the nanorods synthesized are of mixed phases.
