Figure 3From: Preparation of hollow TiO2 nanoparticles through TiO2 deposition on polystyrene latex particles and characterizations of their structure and photocatalytic activityHollow TiO 2 particles. Hollow TiO2 particles obtained by calcination of PSt/TiO2 at 600°C (A, sample C) and those by calcination and preheating of PSt/TiO2 particles (B, sample HC).Back to article page
