A Study on Photocatalytic Behaviors of Activated Carbon Fibers Impregnated with N-Doped Titania
摘要： Activated carbon ?bers (ACFs) impregnated with N-doped titania were prepared via the sol–gel method and sonochemical synthesis. The photocatalytic behavior of rhodamine B showed that N-doped TiO2/ACF nanocomposites exhibited enhanced photocatalytic activity. This result could be attributed to the synergistic effect between the high adsorption capacity of ACF and the visible light photocatalytic activity of N-doped TiO2. In particular, the N-doped TiO2/ACF nanocomposite that was sonicated four times had the highest photocatalytic ef?ciency and degradation rate, owing to the optimal N-doped TiO2 loading and nanocomposite pore structure.

Effect of Zn Content on the physicochemical Characteristics and Photoactivity of ZnO supported Activated Carbon
摘要： In the present work, synthesis of ZnO dispersed onto activated carbon (ZnO/AC) is reported. Synthesis was conducted by using impregnation method by zinc acetate as precursor at varied Zn content. A systematic characterization of ZnO/C materials was performed using XRD, SEM, gas sorption analyzer and diffuse reflectance UV-Visible spectrophotometer. Photoactivity of the materials was studied in phenol removal via photooxidation mechanism. From the study it is confirmed that ZnO dispersion give acceleration of phenol removal refer to surface area contribution. It is no linear correlation of each physical character to the photocatalytic activity.
