| 摘 要： | 采用水解沉淀法制备了纯的和N掺杂的TiO2纳米光催化剂，并用二次离子质谱、X射线衍射、紫外-可见漫反射光谱、比表面积、透射电镜等技术进行了表征。以GaN基兰色发光二极管为光源，研究了催化剂光催化降解甲醛的活性。实验表明，在最佳反应条件下，N掺杂的TiO2纳米光催化剂在可见光下对甲醛有良好的光催化活性。

| Abstract: | Pure and N-doped TiO2 were synthesized by hydrolysis-deposition method. The catalysts were characterized by SIMS, XRD, UV-vis diffuse reflectance spectra, TEM and BET. Using blue-light-emitting diodes as a light source, the activities of catalysts to degradation of formaldehyde were investigated. The results showed that under the optimal reaction conditions, the N-doped TiO2 catalyst exhibited high activity to degradation of formaldehyde under visible light irradiation. |
