Size‑, Mass‑, and Density-Controlled Preparation of TiO<sub>2</sub> Nanoparticles in a Spherical Coordination Template
No full textTiO<sub>2</sub> nanoparticles were prepared with strict control
of the size, molecular mass (PDI = 1.02), and mass density by hydrolyzing
a precursor, TiÂ(acac)<sub>2</sub>(biphen), in the presence of a well-defined
hollow Pd<sub>12</sub>L<sub>24</sub> spherical endotemplate. The formation
of highly monodisperse TiO<sub>2</sub> nanoparticles was confirmed
by <sup>1</sup>H 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<sub>2</sub> nanoparticles
(2.0 ± 0.2 nm in diameter), which showed photocatalytic activity
