Abstract

The titania coating on phosphate surface was made by the painting method in air and at room temperature. The coatings were dried at 25oC and sintered at 150oC, 250oC, 350oC, 450oC, 550oC for 30 minutes. X-ray diffraction, scanning electron microscopy and the cutting method (TCVN 2097-1993) were used to characterize the coatings. The results showed that the coating annealed at 350oC had the high photoactivity in the photodegradation of methylene blue.
