Abstract
Titanium Dioxide (TiO2) coatings deposited using Plasma Spray Process has wide range of application in recent years. The feed stocks used for spraying can be in form of powders, suspensions or solutions. Titania is used as photocatalyst for many industrial applications. The coating photocatalytic activity was evaluated for their performance. There are discussions on the factors affecting the performance of the catalytic activity. The use of Methylene blue (MB) dye as aqueous solution was used for evaluating the photocatalytic performances of the coatings. The phase analyses were discussed with X-ray diffraction (XRD) and Raman spectroscopic techniques.
