Figure 1From: Preparation of hollow TiO2 nanoparticles through TiO2 deposition on polystyrene latex particles and characterizations of their structure and photocatalytic activityTEM images of PSt/TiO 2 core-shell particles. Particles obtained through TiO2 deposition onto cationic PSt particles prepared with cationic DMHB monomer (A) and TiO2 deposition onto anionic PSt particles with surface charge converted by KH550 treatment (B).Back to article page
