Abstract

Abstract: By the measurements of wettability, ξ potential, viscosity and sedimentation, the technique of surface chemistry was used to characterize the dispersion behavior under with and without UVirradiation condition. Photo-induced enhancement was found for the dispersion of nano-TiO₂in water. The photoac-tion highly improves the dispersion and stability. The effect is attributed to photogeneration of hydrophilic TiO₂surface through an investigation of the mechanism.

Key words: Titanium oxide, Dispersion, Ultrafine particle, Photoeffect
