Abstract	Anatase TiO$_{2}$ nanoplates, with average side length ranging from 90 to 200 nm and average thickness ranging from 20 to 60 nm, were successfully fabricated by annealing anodized TiO$_{2}$ nanotubes with different heating rates. The as-synthesized TiO$_{2}$ nanoplates and nanotubes were analyzed by field-emission scanning electron microscopy, X-ray diffraction, X-ray fluorescence spectroscopy, and transmission electron microscopy. To investigate the growth mechanism of the TiO$_{2}$ nanoplates dominated by highly reactive {001} facets, different heating rates were applied appropriately during the thermal treatment. The results revealed that the heating rate during thermal treatment is critical in determining the nanostructure of anatase TiO$_{2}$. The fast heating rate (samples were annealed when the temperature heated up to 450 °C) and the brittle property are the main reasons for the collapse of the anodized TiO$_{2}$ nanotubes. The nanosized TiO$_{2}$ species grow into TiO$_{2}$ nanoplates with the exposed 60 % of {001} facets because the fluorated surface of TiO$_{2}$ species can direct the formation of TiO$_{2}$ nanoplates with exposed {001} facets. The photoactivity of the TiO$_{2}$ nanoplates is higher than that of TiO$_{2}$ nanotubes.
