Figure 1

TEM micrographs of pristine palygorskite Na+-Pal (a) and TiO2-Pal (b) samples. Selected area electron diffraction pattern indexed with anatase (c) of a TiO2-Pal sample and high resolution electron micrograph (d) showing a nodular anatase NP (8–12 nm in diameter) and the planes with a reticular distance of ca. 0.3 nm [11].
