ABSTRACT
Organic-inorganic composite photocatalyst g-C(3)N(4)-TaON with visible-light response was prepared by a milling-heat treatment method. The photocatalyst was characterized by X-ray diffraction, high-resolution transmission electron microscopy and UV-vis diffuse reflection spectroscopy. The activity of composite photocatalyst g-C(3)N(4)-TaON for photodegradation of rhodamine B is higher than that of either single-phase g-C(3)N(4) or TaON. The obviously increased performance of g-C(3)N(4)-TaON is ascribed mainly to enhancement of electron-hole separations both at the interface and in the semiconductors.
