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.
采用球磨-热处理法制备了具有可见光响应的有机-无机复合光催化剂 g-C(3)N(4)-TaON。采用 X 射线衍射、高分辨率透射电子显微镜和紫外-可见漫反射光谱对催化剂进行了表征。复合光催化剂 g-C(3)N(4)-TaON 对罗丹明 B 的光降解活性高于单相 g-C(3)N(4)或 TaON。g-C(3)N(4)-TaON 性能的明显提高主要归因于在界面和半导体中增强了电子-空穴分离。
