TiO2 coating prepared by mechanical alloying treatment for photocatalytic degradation

ABSTRACT In this study, a nanostructured TiO2 coating was successfully prepared on a large-scale titanium plate by a simple one-step surface mechanical alloying (SMA) treatment. The coating was characterised to determine the morphological and composition changes with SMA. The coating was ∼60 μm thick and composed of 5 nm diameter rutile TiO2 particles. The photocatalytic activity of the nanostructured TiO2 coating was studied via the ultraviolet–visible (UV–vis) decolorisation of aqueous rhodamine-B. The results showed that the photocatalytic degradation effect in 5 h of the φ30 mm nanostructured TiO2 coating was comparable to that of 20 mg raw TiO2 under similar UV–visible light irradiation. One-step SMA was demonstrated as an appropriate method to produce a high-performance photocatalytic plate.
