Fig. 5.4. Transmission electron micrographs
of anatase TiO 2 nanoparticles prepared by
solvothermal treatment of Ti(OR) 4 after
hydrolysis with tetramethylammonium
hydroxide. The inset in the upper micrograph
displays a Fourier transform with discrete
spots, attesting to the extent of superlattice
coherence. The lower, high magnification
image shows that the nanocrystals are wellfaceted. Reproduced from [68] with permission
