Construction of hybrid Z-scheme graphitic C3N4/reduced TiO2 microsphere with visible-light-driven photocatalytic activity

265The g-C3N4/r-TiO2 Z-scheme composite was successfully prepared by a facile hydrothermal method. Materials with unique structure have been attracted wide attention and could be applied for removing environmental pollutants. When it was used to degrade the rhodamine B under visible light irradiation, it shown excellent photocatalytic activity and stability, which could be attributed to the synergic effect of g-C3N4 and r-TiO2 catalyst, large specific surface area and the stable oxygen vacancy in composite.
