The Synthesis of Anatase Nanoparticles and the Preparation of Photocatalytically Active Coatings Based on Wet Chemical Methods for Self-Cleaning Applications
Figure 3
(a) Bright-field TEM image of anatase seed agglomerate. Inset shows high-resolution TEM image of anatase seeds in which smaller, approximately 5 nm crystallites of anatase are clearly visible. (b) Zeta potential measurement of anatase seeds used to inoculate titanyl sulphate solution. The isoelectric point of the anatase seeds is around the pH value of 5, which is also the pH value of the seed suspension used for inoculation.
