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

Figure 5

DLS measurements of nanoparticle suspensions that were made from metatitanic acid (0,6% seed quantity) and the subsequent addition of a barium chloride solution. The curves correspond to DLS measurements of nanoparticle suspensions prepared using different amounts of barium chloride solution that were added to the metatitanic acid. Namely, 400 mL of metatitanic acid suspension was mixed with 110 mL of 0,5 M solution of barium chloride, 120 mL, 130 mL, and 140 mL, respectively.
