Figure 4From: Preparation of hollow TiO2 nanoparticles through TiO2 deposition on polystyrene latex particles and characterizations of their structure and photocatalytic activityXRD diffractograms of rutile and anatase TiO 2 and hollow TiO 2 particles through different processes. Curve 1, sample D (simple THF dissolution); curve 2, sample HD (preheating plus THF dissolution); curve 3, sample HC (preheating plus calcination).Back to article page
