高效光催化剂Ag/AgCl膜的制备及其在日光下降解甲基橙的研究

[目的]探索高效光催化剂，介绍高效光催化剂Ag／AgCl膜的制备方法。[方法]以玻璃为载体，采用PVC固定的化学沉积法帝备一种高效的且可充分利用太阳光的光催化剂Ag／AgCl膜，并对该膜表面形貌进行SEM表征，然后在太阳光光照条件下，以甲基橙蔗目标降解物，进行Ag/AgCl膜光催化氧化试验，研究了甲基橙色度、有机碳的去除率。[结果]研究制得的Ag／AgCl膜成膜均匀、疏松多孔，具有较高的比表面积，日光下该膜具有极高的光催化氧化活性，20min甲基橙溶液脱色率达到了94.4％，50min甲基橙的总有机剃去除卒为34.4％；结合吸收曲线推测，甲基橙降解过程是偶氮键先断裂，后苯环打开，最终可完全降解为水和二氧化碳。[结论]该研黄制备的Ag/AgCl膜具有很强的光催化性能。
