Abstract

TiO₂ nanoparticles were prepared with strict control of the size, molecular mass (PDI = 1.02), and mass density by hydrolyzing a precursor, Ti(acac)₂(biphen), in the presence of a well-defined hollow Pd ₁₂L₂₄ spherical endotemplate. The formation of highly monodisperse TiO₂ nanoparticles was confirmed by ¹H NMR spectroscopy, MALDI-TOF mass spectrometry, transmission electron microscopy, and atomic force microscopy. The template was easily removed by treating the sphere with a metal scavenger followed by calcination to give crystalline TiO ₂ nanoparticles (2.0 ± 0.2 nm in diameter), which showed photocatalytic activity.
