| 摘 要： | 利用浸渍法制备了铜掺杂的二氧化钛，以乙酸为模型物研究了催化剂的光催化活性，利用XPS结果对改性后的催化剂进行了分析.结果表明，改性后的催化剂表面吸附氧的提高和Cu＋/Cu2＋的共存有利于光生载流子的分离和界面电子转移，因而改善了催化剂的光催化性能.

| Abstract: | The copper doped titanium dioxide was prepared by immersion method.Photocatalytic activity was investigated with acetic acid as a model reactant,and the photocatalyst was analyzed by means of XPS.The enhanced degradation rate of acetic acid is attributed to increased charge separation and interfacial charge transfer rate on the surface of the doped photocatalyst. |
