Degradation of Methylene Blue by Titania Doped with Transition Metal and Nitrogen

AbstractFor introduction of low energy consuming system in photocatalytic oxidation process, transition metal and nitrogen doped TiO2 were synthesized with urea and nitrate salt of 4-periodic transition metal elements and their photoactivation characteristics was investigated. In order to find out the photochemical characteristics of produced TiO2, we have conducted the methylene blue dye decomposition experiment by setting BLB Lamp as a light source. Photocatalyst of nitrogen doped TiO2 showed higher photoactive effects than pure TiO2 but transition metal and nitrogen co-doped TiO2 photocatalyst showed lower photocatalytic effects than only transition metal doped TiO2
