Pseudo-isotropic mosaic spheres of anatase almost completely covered with reactive (001) facets are prepared via a one-pot reaction. The growth process is mediated by an appropriate amount of NaF under hydrothermal conditions. Due to the large exposure ratio of identical (001) facets, the product can serve as an ideal model to investigate certain crystalline plane effects owing to their pseudo-isotropic properties, such as texture effects. Intensified X-ray diffraction results are presented to show such effects induced by morphology.
