二氧化钛活性炭光催化复合膜的制备及对若丹明染料降解的研究

Investigation on the Preparation of TiO_2-Activated Carbon Complex Membrane and Its Application in Degradation of Rhodamine B

采用以粉状活性炭为主要载体、少量聚四氟乙烯为粘结剂、金属网为支撑基体的TiO2导电光催化复合膜,在不同条件下对若丹明B染料进行了光催化氧化研究。研究结果表明,该膜具有较强而稳定的光催化活性;在此光催化体系中光催化与吸附之间存在一定的协同作用,使光催化效率得以提高。

TiO2 conductive photocatalytic complex membrane is prepared with powder activated carbon as the main carrier,teflon as the binder and wire netting as the supporting matrix.The membrane photocatalytic oxidation of Rhodamine B has been studied under different experimental conditions.The results show that the membrane is characterized by higher and stable photocatalytic activity;there is a synergistic effect between photocatalysis and adsorption in the photocatalytic system,which can increase the photocatalytic efficiency.
