The Synthesis of Anatase Nanoparticles and the Preparation of Photocatalytically Active Coatings Based on Wet Chemical Methods for Self-Cleaning Applications

Figure 6

The change in zeta potential for anatase nanoparticles when titrating the acidic suspension with sodium hydroxide solution. The zeta potential is large for the acidic suspension but drops when sodium hydroxide is added. The IEP seems to be at the pH value of about 6 which is in accordance with the results found in literature [25].
